Its fun doing things like this. (looks good btw, I personally would have gone for maybe a silvery metallicy colour to match the paint, but thats me)
My old telstar had a brown interior, and after a year I got bored of it.
So I removed everything I could (dash surround, air vent, shifter, stereo surround) and sprayed it silver.
Broke the dash up nicely.
Maybe you could try doing some of that flick paint with a red through it (where you dip a brush in paint and flick it at the paper, leaving long lines of paint).
Don't know what your tastes are though.
