I kept thinking this will be a cameo style drawing, except isn't a cameo only a profile? Although I feel like I've seen some that weren't. In any case, I started painting her facial shape and then just kept adding stuff without erasing (for the most part). And when she started looking more classical (almost manly, to be honest) I kept the style more retro, like in the vein of a distant illustration style. I rather like how different this is for me. Things happen when you doodle and experiment!
