You've been making quit a few pretty good sigs lately, except for the smudging ruins them. Really really really work the smudging, spend some time, change the rate, spacing and experiment with certain brushes. Other than that, it looks pretty cool, can I see the stock? Unless it's a render. The smudging on the right is bad, and it really takes from the sig a lot. But the effects are really cool! You should add a light source (maybe the flare directly behind her?) and make some depth, then it would be pretty cool. What font do you use?
Loovee the effects on the left side. The right side could use more..something. The text is a bit meh and so's the border, but that's just me, you know?
