Update

Quality is good, you have got the matte paint matched really well, the wheels look strange now though, maybe some shadow under them and the skirt would get it sitting better in the background, the design is ok, and like i said quality is good however from the rear arch to the back of the front arch looks strange, kinda too thin and unrealistic, not tooney in that sense, just unrealistic, i cant really explain it lol also none of the shutlines look real, they would follow the bodywork in real life, not be perfectly straight, hope this helps and like i said well done with getting the matte paint right

I think a bit more darker and a shadow will make it perfect

looks good, but shadows are missing.
