The mix is pretty cool and well done though the movement is quite exaggerated - mainly the headbopping when it moves forward and down. There also seems to be a slight problem with his right (viewers left) arm in that one of the parts is showing beneath the other for a brieg moment; and the annimation of his right leg (again viewers left side) keeps bugging me though I can't put my finger on what it is.
I'd be curious as to what other ancient mythical creatures would look with a SciFi look.
