I don't want to presume anything because everyone is a better artist than I am. But my BFs company works with an amazing professional minis painter who does their stuff for shows and has done some pointers vids if you want any on different techniques. Aaron Lovejoy is the guy, if you think you'd like any let me know and I'll hunt up the links.
It's not my first mini rodeo, but since I stopped companies (citadel, Vallejo, Army Painter) have released loads more technical paints, so tips and techniques are always welcome!
