3D Thinking

Said by a friend this morning after I celebrated my very first sale on Redbubble. It was a design I wasn't hugely blown away with, my first attempting to properly create something in vectors with proper shading etc. But someone decided it was cool enough and spent their hard earned dosh on getting a phone case with it on.
Attempted a sort of 3D effect with this, definitely needs some work but a technique I'd love to explore more in the future given it has quite a "statement" feel.
