Hm.. I personally think the Pikachu tag is a step backwards. Too many brushes used. The depth, the blending, the flow, the background, fine. Its the composition that just bothers me. There's not a very good balance of colors, and the brushes are kind of boring to me.
Idea, next tag, dont use something you normally would use. Like....the brushes. Make a tag not using a single brush. Then another without using any adjustment layers. See what you might get, might be a nice challenge for good tag maker like yourself.
