Usually I have some idea on what monster I draw is or who they are, that is not what is going on here. I have some trouble with the background shape too. I like the shape of the piece overall. I dont really like the shading on the shoulder on the left, I should have just shaded the whole shoulder. The shading in general should have been less detailed, more basic in shape definition.
the balance of the footing is off too, now I am just nit picking. Sorry axe monster.
