I need some help with pubishing

I'm currently finishing my game and I'm interested in some details:

1. First of all, this is the actual gameplay :
   and I want to know, if it looks fine enough to be published(Sorry for terrible video quality). If not, don't bother reading below.
   
   
2. You'd notice some things in demo, which possibly should be censored. Can I leave them?
   
   
3. Also, I'm wondering about my assets: most of the textures are searched with google and I have no idea, where they come from. The same is with the sounds. I just want to be sure, I can use them.
   
   
4. With this, I also want to add some background music, but I can't make it myself. So, can I just use anything found in my computer?
   
   
5. Next, nothing like "Donsky Productions" officially exists, so can I leave it in intro and jut add note : "non-existing company", or should I get rid of it?
   
   
6. Also, I want to recheck something: the game is made with unity FREE and I want to be sure, I can sell it. If yes, then does Unity get any part of my profit(I just wonder, if it does so, I have nothing against it)?
   
   
7. As long as I'm just a guy sitting at home and making this without having any company or at least an official part, I understand, that not all stores will accept my game. So, I just need any suggestions which stores can I try.(I thought about Steam Greenlight, but as I have to pay 100$ just for uploading and I am not sure, the game won't be rejected, I just have some fear of risk.)
   
   
8. the last thing I want to know is, what will be the fair price for this game and what can be the possible profit?
   

PS: Sorry for wasting your time, but I anyway expect some help.

 

I checked my textures(found them again and checked sites). As the result, most of the seamless textures came from some free "texture store" sites. however, there are some textures, that were modified by me: for example, the textures on my trees consist of two parts: first is the bark, that's found as other seamless textures and another is a leaf part, that I somehow found(they were most likely on the same kind of sites, but also could be on some forums, or blogs) and modified. also, I made some textures with mudbox and sometimes used some images(as stencils) from unknown sources. What to do with them?

About sounds : they are rendered according to the animations, they're used in. I don't have original files. So, can you tell me,how to check them?(I don't want to break any law here... I have to check that)

I forgot to write: I used some unity default assets(unity 4 pro water without pro features and some particle textures). There's nothing wrong, yes?

 

Your game looks really cool to me! I use a website called modarchive.org to find roalty free music tailored for games

 

Thanks to everyone. I find the given information helpful. The website given by frankrs was a big relief(personal thanks to him for that).
And.. I'm actually thinking to do so: first, change the sounds to similar ones, found in websites, I'll save. than, I'll make the list of sources and send it when trying to upload. I'm interested in this: If the publisher finds anything wrong(illegal) there, that I didn't notice, will he just reject me, or tell, what should be changed?(Uploading this will probably be my first money-connected contract, so I may have strange questions like this).

And... about stencils: I had only suspicious one and I found the used image. Here they are:

First is my model, second was used as stencil. Is there any similarity, that can cause any doubts?

 

I think your fine. Another site I get sound from is called freesound.org the files there though you have to read each separately about usage rights

 

Thanks Frankrs, and to superpig: I used it first as a reference and then as a stencil in mudbox (you can notice the same kind of bumps on the model's legs, but they are not a geometry)... As long as it's fine, I won't care about that any more...

 

I have a question about one of my sounds, that I just remembered: it has a short part from the melody from "the good, the bad and the ugly". There's no way, I can find it and use that legally. So, will it be legal, if my friend plays it on an instrument and I use that?

 

I don't fully understand, what exactly "sounds like" means.... Is it the same with little changes, or a completely different music, that sounds similar(in style)?(actually this sound is even shown in the video: the begining and ending of the animation, where rabbit kills the hunter with revolvers)

 

ok, I understand.

 

What about publishing opportunities? On which stores can I try to upload?

PS : There's one more thing: PayPal doesn't fully work in my country(We can buy things, but we can't receive any money with it). So, if on a certain store it's the only opportunity, that won't suit me for now.. However, if you think about any of those, please write even them(they may be useful for the next projects(if the situation gets better) and I will not need to ask so many questions about that any more)...

 

Can anyone help me by naming any possible stores apart from Windows store and Steam? And... Just in case... Can I upload a single game on more than one store, or is uploading something like selling the game to the company(I don't expect this, but anyway...)?
