Mizuki -- Yay, it looks better~ Except the text. The text sort of got worse xD;; It just looks too bright compared to the rest of the banner, now. Although it's sort of better when it's smoother like that.
And I still think that the mosaic stuff is too strong, but meh, I'm just too picky... Ehem O_o So, err... Yep.
Gerri Shin -- Wait, the Pokemon banner you did was animated, right? Cause when I looked at it before, it wasn't moving, so... O_o About that Sonic one, the border on your new one is really pixelated, and it just looks like it was made in Paint D: And I'm not really into animations in banners (possibly because I can't do them, lul), so I think that the animation here is sort of distracting. And the fact that it changes every now and then doesn't really help (like, it slows down and stuff). Although, the generally fluid animation is okay-ish, I guess. Besides the fact that it stops at the end for a while, then loops back to the beginning...
The image is good, ish, but doesn't match the spin-y thing, or rather, the spin-y thing doesn't match the image. Maybe it would be better if the spinning stuff was blue, or if the image was of Super Sonic instead... Oh, and Sonic's hand and foot are cut off at the bottom of the banner -shot'd for picky-ness- Also, I can still see some white around Sonic :x
Marauding Master -- The Infernape one looks nice... Although I have to say that it looks really empty down the sides D: And the smudging (I think it's smudging) just around the render looks like it abruptly ends in a circle-like formation O_o I think it'd look cooler if it fades out a bit more when going away from the render. Other than that, it looks really nice. And I love the text placement, for some reason.
As for the other one, I can't say that it's better than the other one xP It looks messier by comparison, and a lot emptier as well. The focal point isn't really clearly defined on this one (the orb-like thing to the right takes some of the focus away from the render). Although I like the effects on the text, like how the darkness bit fades into the darkness.
Gah, I really need to stop being so lazy and make a banner D:
EDIT: I finally decided to make something xD
Although I was just smudging random things and messing about, I actually like this outcome. I decided to keep this one blue instead of purple like the last two Roxas banners I made, just because blue looks pretty O_o It looks like it's missing something, though. I just don't know what... So, erm, comments or whatever, please :3
