Great work. His burnt half is both sufficiently gory and bearable enough to look at. Definitely an image of Two-Face I haven't seen before. Though, I'll admit, I haven't read too many of the comics...
I like the amalgamation here. Covering the whole body and keeping grey hair like BTAS but the skin is that chard purple/grey color from TDK. As always, I love the brushwork.
Really like the contrast of black and white you used for the background! it makes each side of his body stand out.
