Vaguely oriental, coloured woodcut-style drawing of a female chucking around balls of bright green fire... her determined focus makes me hope she's on my side.
Perhaps she'll do for your character portrait, if you character happens to be female and fond of chucking fire around. Or if you are a GM, she may inspire the creation of an ally or adversary. Maybe you need just the right illustration for that treatise on magical fire...
Whatever your particular needs, this picture gives a fair bit of inspiration for you to conjure with, and it will make a neat illustration once you have found the right idea.
