Looking very nice actually
Good use of the reference to brush your own paint
It's actually looking really good
I think the part where you've added some ground reflections needs a little work though - compare it to your reference, and you'll see it should just get darker rather than any specific reflections
Only other thing is that the shadow looks a bit weird. It gets black when it overlaps the tyres
Perhaps c+p from the paint reference picture
Keep it up
