Nice signature, Maybe needs a little more brushing in the background though, the colours work nicelly with the theme you picked, the font for your name is really good, the bevel suits it really well. The blending could do with some work though m8 as to me it just looks like an opacity change.
hmm.. cool brushing, a bit plain in places, text is allright, i would try and have a few colour variations to add a bit of flavour to the sig 7/10
