Mustang

[Ascarine]

Third Car sig, second on this site, what you think?

[Garis]

BG dont fit to the render.. car is grey and blue, and the bg is yellow
motion blur blending isnt that good..
you need a text then :]
anyway, keep working hard and you'll improve

everything as Garis said,

dude,your sig looks like 1 of million car sigs with motion blur effect, i realy dont see anything special about it and ye, yellow kinda dont fit there, maybe try some desaturated blue for BG
