Yo for everyone;) it is my new work in progress I am supposed well to add hope that you will suggest for me what I am supposed to mend:)
Base:

Work:

i think the red on has to be more horizontal like the black one...and if that is headlight beams i see they look so fake:)

Rear lights will be mended in terms of the reality;] and as for putting cars it in what way to place them so that they are on the even surface?

in my opinion you should but the red one like the black one is because that fits the background a lot better the perspective works...and your headlight flare is too high:)

The first thing to emend is the bg, it is off. That bg doesnt work for that car

My win be crashed and i clean HDD ;/ I MUST CREATE NEW work
