One thing I can comment against here is the focus. I mean looking at the bg and the car itself, it's not blending in too much where it sits on the whole piece.
Apart from that, I can see that you found some huge pair of wheels and they do fit.
I am not a fan of such camber but okay.
Another thing would be windows. side ones with seats looking a bit small and a bit higher than it should be, and rollbars a bit too visible for this whole environment. You would want some minimal tint/flare on there. Windshield is very good except the tree reflection on the side where you need a bit more curve maybe, and less opacity or some simple blending options.
Other than these, good job
