[Hadouken]

First time using pentool in a signature...

[JoShO]

Tad bland, though I'm a massive newb with the pen tool. I guess you could experiment with different size strokes? Being the same stroke makes it kind of dull.

[Derosion]

Pentooling used is too chaotic. You don't really have any sense of flow, also your strokes with it are repetitive and boring.

Use better colors and try making shapes with pentooling, not just lines.
