Left Arm and is the center piece for my sleeve. it is not finished yet and the picture was taken when it was freshly done. the creature is not an actual butterfly. it was inspired by the book, One Flew Over the Cuckoo's Nest. A character, one Mr. Harding, was dousing himself in pills and the author relayed how they resembled green and orange bugs crawling all over him. so the item in the center reads: Alza 18. which is a pill for concerta, prescribed to those who ARE A.D.H.D.
