Nice design!
The open door seems a little too white in the middle.
The wheel is very bright, but I don't know if your going to change the BG or not.

hi,
at this moment, thats looks too toony and squared...
but great potential for the continuation
GG

Thanks guys.
I urged to do better and to continue

I think you should carbon the front lip and centre section, bits that are gloss black anyways to give it a better effect. As for the front rim, I think you should change it as the quality ain't that good. Keep it up though, looking good so far.

Thanks to the advice of BSC have experienced this .. and I must say that I like!
I leave you comment and please give me more tips on how to continue.
And if you have one, I say one! , wheel of good quality please post it.

carbon is made in the wrong way but i've just explained you how to do it
rest is fine mate. keep up..

Well, I hope you don't be mad on me, if I talk a bit about the mistakes
First of all, You should add some refs on the side of lip, and add more brightness to refs on "carbonized" parts, because now they looks not realistic. Secondly, I strongly suggest, that you would add some blur on lip and other parts which you have brushed, because they looks angular.
Then, you could rebrush wheel(I guess I see now a bit brush on it), or find a better donor, because it looks like incerased.
I hope, that in next wip you'll use some of the advices
Then the chop will be perfect, I think

EDIT: By the way, when you push "make selection", set radius to 0,3; With this method, there won't be any edgy places

Thanks for comments and aid guys.
Soon a new update with many mistakes fixes

Here's a small update.
Done a bit 'in a hurry, I do not know if I have corrected all the errors!

Yes, your carbone is too dark for a good realism
for the rest, chooses a style of rims and try to keep it

to the next
