I have determined what I like about your design.
Rather than paint the door handles, door latches, and other small trim, you left those alone and painted the entire door vinyl instead. Makes it look very classy and almost like what a manufacturer would do to a stock "sport" version (thinking MB AMGs or BMW 8-series). I'm usually not a fan of painted interiors because people do only the small things, which comes out looking tacky.
Better still, you left the dashboard alone. I can't describe why I like this, but I do (gives it a subtle tone, separates cabin from controls, I can't figure out what).
I'm still iffy on the actual color chosen (more so because the interior color is MNB, an awkward color to mix-and-match with) but you actually did the details right.
NICE!
