He says hi, and introduces himself as a giant 10 headed dragon in human form. :)

I'm not too fond of his elbows,but those hands and shoes are sort of an accomplishment for me...

Kudos on the hands. Hands are super hard. And yeah, the elbow pinches inwards too far at the top. You've gotta leave some room in there for his bones. His whole right arm is slightly too far away from his body, this stems from the fact that his right shoulder is too far away from his neck/rib cage.
You seem to be going for an anime style, so I'm not going to nit-pick you on the face. Anime isn't my thing so I don't really know what the guidelines are.
His left foot is pretty good(and the right one is too, actually), but I would have turned his foot outwards slightly so we would see more of the inside of his foot than the top.
Check this guy's (https://classconnection.s3.amazonaws.com/523/flashcards/4942523/jpg/apoxyomenos_pio-clementino_%28contrapposto%29-145D3C6F1B07E881869.jpg) right foot, and this guys (http://www.zbrushcentral.com/attachment.php?attachmentid=181505). Other than that, pretty good.

Thanks! Last night I picked up the pencil again, to see what I could do on my sketch pad now that I had a pretty good idea what he looked like, here's what I came up with. :)

The main problem I'm dealing with now is that his head's a bit out of proportion with the rest of his body, but that's part of why I try to practice as often as possible. That last one had fairly decent proportionality. Also I've still got the noodle neck problem, lol.
