I've been trying to come up with another app icon in a cartoonish/anime style, but…I hate it. I feel defeated and I'm a terrible artist and I just want to go ride my bike now.
More dramatic lighting definitely helps a lot. I don't love it yet, but at least I don't hate it anymore. Colors still need a lot of work. And not sure if I should introduce soft shadows and gradients or not. Probably should at least see how it looks.
