personally not too keen on the style, but most of the mods have been done very well

The bg change looks flawless and the rims and all other parts seem to fit just fine
What I would recommend you fix though, is the rear lights. Although they have a matte filter over them, this would still reflect light, so there would be some light highlights on it which flow with the rest of the paint
But overall not bad at all. Keep it up dude
