Pretty good on effects, they match with the tag well, and the blending is pretty good as well. Work on making the effects flow with the sprite, though. Cause' they're all going the like opposite direction o.o Also, work on the lighting, too. Maybe add a nice glossy floor effect. I dunno peaccceeee.
Well, tone up the effects a little, ´cause they are kind of dark, retire the text, it really is unfitting, the negative space is good, but a little less would be better, probably add some soft brushes at different blending modes if is still too dark after you toned it up, still, nice for a first sprite tag.
