So let me say that the pic is scaled to make it lighter to post on forum, at full res carbon looks good IMHO

This is a crop from the full res pic:

Damn I'm looking for a good donor for rims and BG...

Ok finally founded good wheels

New update:

Nice job I also search BG for this

imo carbon should be a tad darker and when u find a bg get some refs on it, rest is looking good

Yep Zero, I'm just waiting with reflections cause I've not founded a good BG for this chop.

Ok BG finally founded

Not bad: It will definitely be a nice chop...
I was expecting a total rebrush, instead you decided to play with filters and patterns, as well as with C&P and the shadows...

However, some adjustments to give you the reflections, and the shadow is to be improved, but it should not be very difficult: it reflected the new background very similar to the old one, and needs only a shadow darkened the side...
