AIN'T THAT SWELL Skeleton Hand Illustration

I was recently approached by a good friend of mine Mitch (who owns the coffee-shop Silver Bean in Newtown) about doing a t-shirt illustration. He needed a shaka'ing skeleton hand, with the text 'AIN'T THAT SWELL'. 
"Sure..." I thought. "...we can do that".

So I spent a while looking at my hand, analysing the mechanics of a shaka.
And then I sketched up some skeleton hands, and made the whole thing fit together.
