Not bad, but there are some mistakes, low resolution (should be bigger then 1024x768), wheels are too big (doesn't fit), mask is low quality and little yellow, color is unreal (you could let base color), side skirt is "broken" (you should adjust it), rear bump is too big and lights doesn't fit, looks 2D

not bad nice work
and agree with STANKAR
4 me it is 5/10
keep it up

Not bad? Of course not, even at the point is, especially the lighthouse on the left ... Search cars in this perspective view and then see this error brutal, in fact repair the original! You are very mature yet, but with time you will notice this kind of errors, not to mention the rest.
Remains well and see the tutorials, they help.
