for the hair, maybe you could make it blond, but give it light brown streaks through the hair. That might darken it up a little.
The artwork itself is great though. Even if it doesn't look much like Alexi.
Yeah true, initially it wasnt going to be any band member in particular, but I thought with the eyeshadow it was kinda lookin a bit like him, and with the straight hair and all, so ill fiddle with it later on . Or I could just use a photo of Alexi that would look more realistic eh?
