Pen tooling could be a LOT better executed. Good job for trying a new style Sarad0m1nz- but the cutting is a bit poorly done, and you can see the edges don't fit around the render.
Smudging is nice, you could blend it better with the main focal though...
Remove the border :3
And text could be improved... it shouldn't be something to make as indiscreet as possible, instead it should compliment the signature and actually add to it.
