Meh its the first time i've really gotten the technique to work well for me. Just keep practicing. Smudging is easily the most useful tool when it comes to sigs.
Not bad for just getting back into it. The smudging is mediocre at best, try to mix it up some and play with the brush settings. You can get some amazing effects. Text needs work and so does the background which at the moment is very plain. On the plus side i think the colors work well (but could be better) and the render blending was done well.
