That's a really great looking portrait, I particularly like his facial expression. It looks very well done! But, I feel the urge to ask one thing, if you don't mind! What do those hands stand for that you seem to have sketched over the portrait? Or are those supposed to be a banner of some sort?
I quite like this representation of him. You show him within his place in society; small, overshadowed by the taller men that serve to protect and even mock him. Colour scheme is great, as is the addition of the lines, as it creates a framing device that makes the composition overall balanced and arranged. Love the colours and composition!
