While I'm not a big fan of the main show, the movie was fairly good.
Your drawing really did capture the sly condescending-ness that is Fizzlepop/Tempest.
Of course you don't have to listen to my suggestion, but the impact of this drawing could've improved some if the background wasn't the same colors as the character, a different shade or color may work but the first thing I was drawn to was the background, which clearly may not be what you're going for, the outline helps a lot and it does even out the background but it's also fun to experiment with colors and junk.
Aside from that your blinding, color choice, ect. was amazing, the piece binded well together in the end, even with the same color background.
