nice pic. i luv One Piece too, although i'm just into the anime, the characters just seem more lively. also, i think luffy changes his shirt style to sleeved after he got that scar on his chest, although it could be in just the anime.
As much as I might disagree with you about your opinion on most Shonen anime in general, I will say that this is a pretty damned good picture of Luffy. The pose, the expression, including the stretch ability a bit all fit with the personality of Luffy's. The flag looks nice and well done, too. Though the only complaint (or rather small nitpick) is that the scar on Luffy's face seems to be missing. But other than that, nice work dude.
Pretty big fan of this myself. I'm about five months behind on my reading though. Shame, cause I do pay for the legit Shounen Jump subscription to read it. Their online viewer however is really unpleasant to use though. Takes a lot of the fun out of it.
I really like how you draw luffy in that boney appearance, I mean some good mangas like Naruto, Scott Pilgrim although it is a cheap North American- Manga Cartoon created by a canadian who invented a popular style thats been past on to those who would inherit his style for potential projects, and a primary but Really great manga favorite of mine FullMetal Alchemist! do you know sir daniel fortesque from the playstation game series MedEvil? I bet your depiction of boney knight will look cool.
