I really love the small animations. How in earth could you fit so much detail in such a small space? 
What bothers me a little about thes is that he appears to be in a sitting pose because both of his legs look like they're a pixel too much in front.

Very nice piece, congrats. Maybe a third color on the clothing (I know that there is the dark outline) for highlights or something, could have made it look more plastic. On the skin you also used three colors. 

The transition from redish to green is very cool and generally the piece looks really smooth. I like that you used that "fake AA", I don't know how it is called.

Wow, this looks great, very polished. 
I can not imagine how long this thing took you

I love the lighting on this knight. It really makes him look plastic and almost three dimensional. 
There is one thing that slighty looks off. His legs are bent in a kinda weird way and his general pose doesn't look that strong. Shouldn't a paladin stand heroically?

But anyway, a strong piece! 

Thank you for the feedback :). I didn't think about the idle animation that much. I saw that grey pixel just after I posted it and now it annoys me a little :P  

I look forward to create more stuff!
