I blush very easily & whenever I'm the least bit embarrassed, or emotionally stirred in any way really, I begin to resemble this AlphaBot, glowing ears & all. Unfortunately I can feel it happening & that just makes me more embarrassed.
I had fun doing all the radiant gradients though! I'm starting to hate gradient mesh just a tiny bit less, though it's still weirdly unpredictable. It does allow for a lot of subtle mixing!
I also experimented with multiple strokes on a path here, to create a fake gradient for the fingers. It sorta works!
