Ok now its time for me to seem like a bad guy lol.
1.Background isnt good sorry try something a little bit more complicated and looks a little better the colors just clash. =P kinda looks like you did a weave effect and colorized it.
2. like I said in step one bad choice in font it looks out of place and doesnt match your sig in the least.
3. Get a render they make it a little easier to make a decent quality signature and they arent too hard to use I can help any if you need it.
