There good, but something about your avatar you are using makes it glow. I don't know. I still think Riku is awesome, so that may help.
In the first one, the text style is getting kind of overused, but it´s my favorite n_n. The second one is good, nice idea of using the lower part for the focal, and the left side looks like a border o=, but I say sharpen the leg a little more, it looks a tad blurry =|. Third one is a tad dark in the render, try to bright it up a little, and the text, there is something bugging me about it, probably is the area around it =/. Also, I love how you added the color blobs :3
The first one is my favorite too. And color blobs ftw. :3 Added another... More to come, but I've got Biology homework. *gag*
New one is nice, but either is low quality, or the light makes it blurry, also the text is looks kind of slapped on, I say put it behind the light source, unless you want it to make the text more noticeable :/.
Added another. I'm open to request... Just PM with the image you'd like (high quality please. I can up the quality a bit, but my magic is limited) and the text you'd like. (not too much)
I actually have a request XD I'll get that to you later. But a few of the first work seems LQ. The last one's good though.
these are niceee. I especially like the fourth one down because of the colors, but I like all of them, and how you managed to throw some originality into this style.
