Could you upload the original?
The main problem is quality. Did you save in highest quality?
Wheels are blurry but nicely fit (kudos!). Did you reshape them a lot?
The paint doesn't have any reflections from the new background but good you tried putting some on the new background.
Adding black lines to all edges isn't really a good idea, would at least need a brighter red line beside it on most shutlines.
For a first try this is quite nice! Keep it up
