I like the camo, a bit toony at places, but still, well done .
The windows have too brownish tone to it, they need to be more desaturated and I think the side windows should be just a bit brighter. Also noticed that the wheels have some jaggy lines, I think what caused it is that while you changed the wheel size using ctrl+t, you also rotated them, which causes those jaggy lines. Next time, do those things separately, first resize them, then press enter and again ctrl+t, then they will stay smooth like they should
