the last one reeks of confidence, and its awesome to see you playing around with interesting shapes in the designs and such.
my only crit, and its not really even a crit, with the guy in the foreground, his cloths are all the same value, this could have very well have been intentional, but i think it might look better if there was some contrast between his different cloths? or if it was a uniform or something maybe some kind of pattern or insignia? either way, it just seems a little dull of a design at the moment, the rest of the piece is perfectamondo!
oh one more thing, i notice you are using quite a lot of rounded off kind of shapes, they are great, but if you got some sharp edge shapes going on too it might just make them both more interesting, contrast in everything right? just a suggestion
i dont know what that organic, fleshy pillareque thing is by his shoulder, but i absolutely love it i also commend your ability and patience to render those finnial designs!!! btw is this who youre drawing? (haha! sorry )
