Not to be a curmudgeon but don't flames work the other way round. They are white at the base and red at the extremities.
I also, personally, don't like the colour scheme. Purple flames good, blue roads bad. I know that the blue/purple paint scheme you are happiest with, but seriously, what kind of bright wizard would wear blue. Assuming he didn't have an accident when doing his washing with some jeans.
I think he would look better with either very light yellow or orange clothing.
Black background defo better for snap.
