It looks pretty good for first signature. I would work on blending, and the background. Text can also need some work.
And then make sure the lightning is correct.
But read some tutorials, and you'll become a master within no time.
ok thanks, will do. Do you know any good tutorials?
I first started on SigTutorials.com | Signature Tutorials -> Tutorials
Then I moved to some better places.
