Already rated your first one, so I'll do the second: Looks nice. The bg is alright (could use a little more "flavor" though) and the render fits well. Not a big fan of that border for some reason. The text is on the simple side, but it works just fine that way. 8/10.
Hmm i like both of them. the text is ok but i love the BG on both and the renders are not my favorite so 7/10 overall
Already rated your first one, so I'll only do the second: Great bg, and nice choice of colors and render, but the sparklies on Vivi just don't look right, and the Dark Magic text looks like it needs to be AA'd. Other than that, awesome job. 8.5/10.
Rating your last one Bear... Looks nice. The fractal brushing's cool, the colors meld nicely, and the sparklies are a nice touch. The text could have a different color glow/stroke though...the white stands out a tiny bit too much. 9/10.
