I dont like it.
Heres what I think is wrong with it:
- missing a border, they always help - even if its a simple 1pixel black border.
-the bg looks horrible. Im not sure how you got it, but yuck. doesnt suit trips at all, really
-the choice of pics and the placement could be a little better.
-the symbol in the middle doesnt quite fit there. Maybe add some effects to it, like a wind-blur or something.
Otherwise, I do like the text you have used in it. That suits the sig rather well. but I think you'd be best off starting again...
