Ermmmmmmmmmm.
Okay I have another suggestion. xD; Start over from scratch in terms of blurring. Like, make a tag. Don't blur it. Like. Anywhere. xD;;
The Chii one is what prompts me to say this, because you've blurred her in all the weirdest places, and that really throws off your depth. I can see that you're working on your colors in this one- because heaven forbid, there's more than one color! :D But um, the sharp-blurry-sharp of the focal just makes the whole thing really low quality. And the background effects are pretty, but.... plain. And oversharpened. Okay so things FARTHEST away from you should be blurry. AKA: the stars. Things CLOSER to you should be sharper. AKA: EVERYTHING about and on top of Chii. Including her hair. <_<;
And maybe the png itself was just low quality. D:
Black Rock Shooter huh? Well, the scanlines help with the flow, and I don't really mind them, but the opacity needs to go down. Also, the whole thing is just blended... way too much. Like, it's over done. I see your smudge settings, and like I said before: Trash them. Dx They make everything look blurry and they don't look good when you sharpen them. Dx I dunno though, with the settings it's more style oriented, so maybe I just don't like your style? D:
Other than the colors though, I like #6. :I
