Haha that is so awesome yet creepy! I love it! So where to begin? Well for starters it looks incredibly realistic, especially considering it is so small. The little details are pretty amazing and I still wonder how you pulled them off. That being said, you CAN see some things wrong with it. There are little off details, and some that should be more define than others. But all in all it is amazing. I would love to know how you made the hair so perfect, that is what is really standing out right now. So i finish this off saying very realistic, amazingly small, minor problems that are rendered almost unnoticeable, and one hell of a piece of work.
I had to sign up an account to tell personally (well, virtually for now) what an awesome work you are doing. My husband is a film director and a big fan of BatMan. He has a toy of Joker that has been with him for years. unfortunately, his nephew accidentally broke the head the other day. When I saw your work, I just fell in love with it and I must say it's the best Joker rendition ever.
I'd like to repair his precious Joker toy and would like to humbly inquire if you can help. This Joker head would really drive him to happiness!
Hope to head from you. firstname.lastname@example.org Manila, Philippines
