Picture 2 would be better, though the suit is so much like his regular suit, so it might not be different enough. And yeah, they should put the eye inside the pumpkin, so you can see it through the face holes, LOL!
A headless horseman pose would really rock though, too bad there's no way they'll repose a variant like that. Otherwise, totally, pumpkin under the arm, or maybe in his hand like he'll throw it (doesn't the headless horseman through his pumpkin head? Maybe just in the Disney cartoon)
I'm pretty sure there have been versions of the Headless Horseman with the jack o' lantern as a head, which is what I originally pictured when I saw talk of Pumpkin Eye Brawl. Since Eye Brawl's eye does come off and make him headless, it makes sense. The Headless Horseman was known to throw pumpkins, as well. I thought that was a cooler power than Eye Brawl's current abilities (which are lacking, IMO).
