Diamond Emma is a long-time coming, but I wish the hair had more of a blue tint. It's looking like dirty crystal, not diamond. A blue tint would help it stand out - actually, the whole of her diamond skin having a blue tint would help offset the white of her costume. I think the package art nails it.
And if they were going to include an alt head, one of the 97 ones would have been nice.
None of the other reveals interests me on a character front. Owl looks cool - and there are Mandarin's claw hands true purpose - but I have zero connection to the character. The fact that Hypno-Hustler gets more original sculpt love than most female characters with their painted on costumes kinda pisses me off.
