Alright, so I needed to just go ahead and post these. I didn't get as many done as I would have liked, but it was a good excercize and I really enjoyed the challenge of communicating a character through gesture and pose.
The two Jekylls on the top left are fairly standard fare, with their corresponding creature below. however, the idea I liked was the Jekyll/Hyde combo of an old man trying to create a serum to grant him eternal youth. The result is an attractive young man... with a thirst for blood! BWAHAHAHAHAHAHAHAHA!!
