Avatar 8/10 - I prefer this one, and if you did the cutting yourself then you've done a very nice job.
Sig 4/10 - Sorry, it's certainly original but in the end it is just a few tech brushes on a plain canvas. If you used one of your, quite fantastic, photos as a sig and then maybe layered a deviantART, RedBubble and Facebook link over the top I could see that being a 9-10/10.
In other news I've made myself a new sig. I liked my old Pokemon one, it was cute, however I felt Karim needed some love. Looking at it now I notice the text in it is difficult to make out. Oh well.
