It looks like the Harvey Dent side has a slight lazy eye. I don't know if yours came like that, but one of the pictures makes him look like the Dent eye is kind of staring off into space, while the burnt side is staring right at you.Why? The TwoFace head paint and sculpt was one of them that didnt need any work out of box it was perfect as is... As long as you like it thats all that matters I guess... I dont though burnt side is to dark now... The burn covers more of his face then it did in the movie with the extra paint... Theres also something off about that Harvey Dent side...
the joker is not a repaint it is a 100% brand new sculpt which around 4 were ever made and cost a good amount of money. For your two-face shirt you can do what i did. I bought a charcoal pencil from a craft store and then took a q-tip and rubbed it in slowly. I would not take a lighter to it.
