The overall mood is really nice! But although I know it is really hard, and I can't do it myself, the car itself doesn't really look like it is standing 'in' the rain. I find it real hard to explain it right but I hope i made myself clear :$
EDIT: But I want to make clear I really like the picture haha
I know what you mean, as I sayed it's my first one so I'll improve if possible, raindrops on the car body didn't turned out well in the moment so I hope that next time it will be a bit better
