This is superb! You've captured the shine of the latex outfit perfectly, and Harley's evil look aswell: a devilish mix of sadism and madness, but seductive at the same time. The blood splatter looks great, too! Dried-up, crusty blood underneath her hip, and lighter, fresh blood splatter are to be found near the beginning of her stockings. A nice little detail, that. A question, if I may: Did you use a reference for te guns? If so, which?
Now to the rest of the picture. The mist-shrouded skulls look suprisingly real, the details on them are aplenty, AND you've captured them in multiple angles aswell! That's quite a feat for anyone! Good job! I shall not undermine The Joker's part in the picture; he looks... well, like The Joker! Complete with cartoonish facial features and disturbing grin, he looks about ready to disembowel me! This work is truly a sight to behold in every way! I look forward to see more gold from you, Bella!
