You should make the render smaller, or make the canvas bigger. Right now you've kind of got a floating-head going on with the render, so you should sharpen up something connecting the head to the rest of his body. Left side of the tag looks a little plain compared to the right, so I would add a fractal or something there. I like the placement of the current fractals, though. As for the color, it's a little monochrome; you probably should of kept some more of the original color, before the filters/gradient maps or whatever you did here. I also think you should have lowered the opacity on the drop shadow in the text, and moved it a tad bit closer to the text. Rest looks good though, I like your style
P.S. Was the graphics group +sfx ever on a site called GFXRaid? Because that was my very first GFX group I was ever in, and I was there with a few other guys like +sfx.Burn and some other kids that I can't remember. Not sure if it was the same group, though.
