I actually like it. The Hardwood backround and Gil coming out of the smoke- agent Zero and an explosion would have been better than smoke and gils name but that isw a great Idea and keep at it!
That's pretty good for a first sig. If I were you, I'd would probably get more fonts. Check out 1001freefonts.com or dafont.com . Also, you should probably put more into the background, it looks kind of plain but since it's your first sig, there's always room for improvement.
