Common Sig

Well in consideration to better or worse of which ones you've created that I've seen, the Kanye one is the best.

This one doesn't have much depthm and you can see the drop shadow or something similiar. The text is done well, they layout is good but the yellow doesn't match anything. I think you should just stick to white.

The bg is plain but it looks good. Though as I said it's lacking depth and an interactive scene. Your Kanye has negative space to the left which creates detph. Also the splatter brushes give more to the bg so it isn't as empty.

Oh yeah and also leave some of the natural color. The monitone on your render really cuts down on the depth and realism to the sig.

Ov'er all it's nice and simplistic, though the left side needs some work to make it not as dull.

That border next to your old sig gets way to repeatitive. Hurts to look at. XD
