My first major chop!

Any feedback is encouraged and welcome, I'm still learning the ropes!
BASE:

CHOP:

EDIT:

Not bad for first.
Chop is clean and You try make atmosphere, it's good. I like new wheels.
What is wrong?
- car has bad perspecttive on new background,
- stickers aren't realistic (should have better shadows)
Next time make more changes or if you wanna make fast stylisation like this, add it to "Quick" section

Thanks for the feedback! Still learning the ways around!
