Quite a unique idea and nice executions, the shapes seem appropriate and the composition looks good with the opposite curves which is very nice and Blizzard-y. The icon feels a little dark, and I think either stronger highlights or just generally lighter tones might help. Also the middle triangle could maybe be slightly bigger just to draw focus. Other than that it's well drawn and I like the dotted detailing on the top right purple section and the material on the ball looks nice with a good lipped effect on the rim of the centre ball.
