The text IS a bit hard to read. But I like the tag overall. It has good colors and just looks good in general. The only thing I would even consider suggesting would be to tone down the light on the upper potion since it is coming strong THROUGH his head and coming more out with a full blow lighten if you want it a little lighter... like an overlay. But really, nice job with the colors and texture A+.
You seem to have 2 light sources, his figure and his head. I'd just pick one and go with it. The BG is nice, the colors flow smooth. Nice tag.
The light at his hand is signifying some power I would imagine.. or some bling (rofl). But both seem a bit overpowering still.
Light source could be a bit stronger and you could add some more effects. Colors and texture are nice, flows nice, too.
