okay...well i dont know if im making myself many freinds when im c&c-ing on other peoples stuff like i did back when i did that....but:
first of all i have to admit that the "stock" pic is a already "faked" one...
there is a detail most of you are forgetting about...and thats the shadow the front tire has when its turned in like in your pic.
...arrrgh let me show you^^
*Here will be the pic where i try to show you the shadows*
also the color of the rims in your versions have too much saturation, so it looks a little bit unnatural...try to gear to the color of the brake behind the front tire
-> the same for the banner between the wheels, too much saturation.
and one thing is a "eyecatcher" ( =) ): the complete front of the golf seems deferred...i dont know if you tried something like a "chop" or so^^
BUT
i think its a good one though, because its not that OVERtuned....restrained but not too flashy.
Remeber: English is not my mother tongue, so if i said something that seemed "personal" or whatever that is bad or hurting...i dont meant it, i just wanted to express my opinion about the work..nothing else.
