wow, thats quite...creepy and cool.
so, is this thing a horseman? hmmm, odd.
first of all, his head seems like a hole. does he/it have a head?and if so, does a face reside on top of it?
also, while the main drawing is awesome, full of priapism and quite detailed/creepy, i believe that the only thing that is not shown clearly here is his head/face. and thats bad.
the preliminary sketch on the right side shows a more detailed depiction of his head/body posture/size in general, even if it is less detailed.
i would love to see his female counter-part, this would be interesting!
good drawing, man.
