I dunno, instead of purple, perhaps throw in a few missing chunks + some brown on the edges? Also more hippy stuff, the more peace sings etc you can give him the better. Jewellery etc. Right now he looks like a Japanese fisherman. :D Another quick paintover to show what I mean. Oh and hippie.
So, that's what I changed. I didn't want to make his obnoxious with his bling or flashy clothes, because he's still supposed to be wise. But, I really liked the torn cap edges idea. They really push his age, in my opinion. The shirt's new colors are a lot better, in my opinion. They're much more hippy and much less…
