This is a pretty nice sig man!
**I love the use of the second image, to the right. Gives a really unsteady, "Here's Johnny!" look about the sig. Love it.
**Border. Nice idea using the '16:9' look, but your sides are bare. I'd put a 1px black border around it, to make the border complete.
**The 'Hi!' text being diagonal, I don't like. I think it just sits out of place with the rest of the sig.
**Simple design. Nice use of arrow brushes. I have them, lol.
Overall some nice work man.
