I actually think its lovely with not a lot to criticize about. 
He will honor his words; he will definitely carry out his actions. What he promises he will fulfill. He does not care about his bodily self, putting his life and death aside to come forward for another's troubled besiegement. He does not boast about his ability, or shamelessly extol his own virtues. - Sima Qian.
A nice effort.

Re: the feet - Some great books for drawing lifelike humanoid figures with good sections on things like foreshortening may help and are...

Gonna go to bed in a sec, but I *had* to draw something today;
First off, lemee introduce you to Red Goblin (union hero)
And this is the quick sketch of him I did about an hour ago:
And finaly, a very quickly coloured section of the picture:
2 things to note;
1) my scanner's temporarily bust, hence why I had to take photos
2) this is my first full 'lifelike' human in several years that hasn't been a still-life of a real person. Most of my work latly has been anime / own style (which explains the hair ^^)
This one is in order to get the proportions about right for a full body.
So, any CC (constructive crit) on the proportions is more than welcome.
I know the feet are odd, btw, I didn't spend much time on them =]
