Losing sprite quality after combining all sprite into one single .psd

So i have a 2D scene with a mountain and at first i just using 2 picture which i rotate each other so it will match the end and the beginning and put it all over my scene and i think since i not moving the mountain picture or do anything with it i willing to combine all piece into one single picture as .psd or .png (it is vector picture from illustrator)

so my single mountain picture is in 800x125 resolution and i combining 4 piece so the full size for my whole picture will be 3200x125. but when i put that picture into my scene, the picture becoming not sharp and blur, it looks very bad... any idea why?

here is my two psd picture (in onedrive)

note: level1mountain is simply extension from mountain-1a(i just duplicate it and flip horizontal)

oh and the only reason i'm doing this is because i think it will be reduce draw calls since 4picture becoming 1picture so from 4extra draw calls into single draw calls (am i right?)

 

Change the texture import settings, specifically the maximum size.
