A little over sharped I say. The whole ripped off part in the left corners looks terribly awkward and nasty. I suggest if you're going to do something like that, try to make it go with the color scheme of the rest of the sig.
Trust me, I would've gotten a better C4D that matched the colours if I could fine one with those dang colors. >.< EDIT made a 2nd version w/ Abstract C4D that better complements the tag (kinda). :3 (Also faded the sharpening done on the last layer)
I agree a tad oversharpened. V1 is the better IMO has good effects and flow. The Depth is great don't change anything with the depth. And text?!? =/. =3
Yeah, I should upload a version without that extra sharpened layer I added >.< I tried text, and it killed the tag, so I just left it with no text. =/ Meh? change what exactly? * is confused if this is a grammar error @___@
Needs contrast in the back to create the illusion that he's /still/ standing in front of something rather than just looking at a clean, solid image without any depth. Also needs more variation in effects. I like the spark down there. It would be interesting if you played around with them in creating more of an /explosion/ at the bottom, not completely, recklessly engulfing them, but serving as something with more likelihood to catch the eye. Next, is color. Either add in some vibrant shades, or some pastels to make this little one pop out its womb. Then play around with their compliments, and opacity variations. At the moment, even with the edits, it still feels one dimensional and passive.
Version 1 looks a bit better and at an interesting rate much more, but there's always the contrast that needs a little help on really, make it to where it's more to an illusion, rather than be a stock just standing there. It's good, but needs a bit more work on.
