Not a bad likeness. Requires temporaries, and has at least four loose pixels, but I THINK the rest is logically solveable. Requires at least two places where you have to realize you have floating pixels. That is, the final solution will be either A B or B A which means options C through H can be filled in with negations. Hopefully that makes sense? Trying to explain how to solve it, rather than just giving you the locations of those loose pixels. Good luck. VERY difficult, even for experienced players.
