plz comment and suggest some error in this render.
I would recommend watching Tim Feher's automotive webinar (https://youtu.be/Wen3kO-_1jA).
+1 to what Josh stated. The Raptor looks great but it needs some dramatic effect as explained by the webinar presenter.
Yep- it needs "drama". Tim's webinars will set you in the right direction, and he's the Master! For whatever it's worth, I've used this backplate on numerous projects. A bit over the top, but just play with it as it's a fun backplate and it adds a lot of drama. Hue adjusts easily in Photoshop. You need to play with the environment HDR's as well to give your renderings a kick.
And always remember, there's no such thing as an "error" or "mistakes"!
