hello deeheks, thanks for criticism. ı am using high resolution textures so many times that's why file sizes are little high and ı can do better with scale on the stairs you're right. ı'm just trying small polygons all the times so doing my best there. but still some objects really getting high polygons. as image ı can say like that; it's about with your color correction actually and that is depends with your correction always. ı am a new creater also will be better with time with a lot experience. as final ı am just doing them all as fun, ı have no any claim about this on topic.

the scale of those stairs
the texture quality vs file size
and overuse of props
Hence the downvote, but please keep it up, there's hope :D
