Improvement suggestions car game

I want to ask wether someone has improvement suggestions for my little car scene.
I also search for a unity asset with which I can implement the car physics. (If the car is too fast in a curve a "break out" animation should be played)

Here is a screenshot.
I'm looking forward to see your improvements.



Waterfall and snow are particle effects

 

It really depends what you are looking for. Going by the screenshot it doesn't look overly realistic so I'd steer away from worrying about those & aim for some more cute/cartoony games.

You could have some animals on the road (cows, sheep), going past the lighthouse it could be very dark (night time) with a light beam sweeping across the road at intervals from the light house, water on the road near the waterfall that makes the road slippery & some boulders from the cliff that need dodging, fallen trees across the road or even trees that begin to fall just in front of the player, snow could reduce visibility & make the road icy.......

They're my suggested places to start. Good luck, & post a link into the next Friday Feedback (on the design forum) so we can all have a go & give more feedback.

 

@tedthebug Awesome, that is helpful!
