Number One: Very nice. I would rate it maybe an 8 out of 10. The colour makes the signiture so warm. I like your use of brushes and textures. The font for your name is so nice, what's it called? Number Two: Also nice. Maybe 9/10. I like this more because it has balance. You can see it has some dark warm colours, and some dark cool colours. The font, not so much, but I tihnk it looks good with the signiture =]
motion.blur.4ever? ... Anyway, erase the motion blur from the girly's face and darken the right side a little. Fix the text a little. Try to use methods other than just throwing it on overlay. xD Darken that dude's face a tad; it's much too bright in comparison to the effects around him. I see you darkened the edges a bit in here, but do it some more. IMO, the text would look better rotated. GJ
I like the first one, but (and this maybe because of my vision) the girl in the top sig blends in a little too well to the colors, and I'm having a hard time trying to tell her apart from the background. The second one is better though. You've got a good grip on the emotion; the background seems to fit his mood.
Time for some cnccc~ For the first one. It isn't that bad, but it's not really too good. I like the warm colors you got on it, fits the style of the tag itself. Now the motion blur effect can be lowered on opacity. Make it in the 30s lawl. The text positioning is pretty bad. Don't add any text. That's your only flaw in tag making xD The second one is better. It looks nicee. The paint splatters are done nicely imo. Try smudging the bottom part of the render a bit. It makes more flow I thinkk. You can make the colors of the render a bit more dull because the colors are too bright and get on the tag too much. Raise the opacity on the text. Otherwise, hawt sigs~
