Sinestro Corps Joker

Okay, so I came across a very interesting concept/drawing by Gaff1229 the other day and just HAD to make a cubee out of it. Here's the [link] to the original piece. The cubee is all me as far as actually re-creating the template; however, the template design IS based on the Heath Ledger Joker done by Adrian-Nation (found here [link]).
As for the face, I chose to use the old Batman: TAS Joker for several reasons. For one, Mark Hamill did his voice and that's just all kinds of awesomeness. For two, I feel like a smart/intentional Joker is far more fearsome than a random Joker (not to say that Heath did a less than stellar Joker). Also, I liked the cleaner, less homely look better.

So, what do you all think?

Character is (c) DC Comics (as far as I'm aware).
