I don't really like the scan lines in the top right hand corner, and I really not a big fan of the quality on the guy, and I can't really see many effects going around/on him, nice try man. Lookin better, still not a fan of the text, it seems too simple for a signature like this, try experimenting with things like the size of the font and bolding and stuff. I find this signature to be a bit too small, and the text is just a bit too much out there, also the effects are really mild on this looks like you just slapped the photo into the white canvas and did some minor smudging, try giving it another go.
K, well, may I suggest having a back ground and not just a plain color? If its a plain color you have to make up for it with effects, which this signature also lacks a little in. I don't like the blue piece of the sparks brushing or the brushing to begin with. But mostly the blue piece. Your render could really use some blending, I'm mean like seriously. The text just needs to go. On the lighting, you should have the brightest spot on the focal IMO, unless there's major light source already on the focal then use that to set your source. Also have dark places, they are as important as bright ones.
past the render in multiple times, and make sure it has flow. That way, it has the color of the render, because you pasted it more than once, and flow, which is always good.
V2 of my Transformers SOTW sig. Do you like this one better? I reduced the smudging, recolored it, added some C4Ds, and changed the text. CnC please.
Nice concept there Tiger, just I am not a fan of how you put it together, the text is too blurred and the death line or what ever it's called is too thick, try looking at real life examples, most are quite thin.
C4ds didn't help this any, pick less solid ones. The smuding is better, but I still don't like the left hand, my left. The text well, lets remove it until we get other things in order. You also need a light source on this one, since the dude has a shadow on his right side.
Why don't you like the smudging on the left hand? It follows the flow of the arm down and to the left... I'm not sure what else to do to fix it.
