Here are two I made tonight. Yes, I know the face looks pixelated. Tried some weird techniques. CnC Please...
Don't like teh render for the Sasuke one. Ghost rider one looks pretty cool though. I like the sketchy feel.
The signatures are pretty nice man but your text is really going down the drain man, really work on your text next time, StarWars text and Anime doesn't really mesh. The Ghost Rider signature needs a bit more colour and fix the text.
Any other text I've done was nooby. Ask any really good GFXers and they'll tell you Im getting better. P.S. Not the people from this site.
I know you are getting better, just you should work on your text, your experience with effects are evolving quite rapidly.
Its called hard work d00d. I read tutorials like 10 times a day. Sooner or later, Ill be able to do them all myself. I actually did this one without any tutorials. But, I can still get better.
