Looks Time Consuming...
Gotta give you props for the amount of detail, not just in the colored works, but also the pencil drawings...
I get the feeling of Video Game Art or Concept Art going on, not quite at the level that you normally see for such things, but keep at it, it's the only way to improve.
...It would be nice to know the back story or more about this character to asses his personality posses, but perhaps I missed that in another of your submissions in which it might be stated...
hope that was helpful...
