I like the addition of glow to the outside of the pumpkin. I might have left the underside un-done, though, as I think it makes it float when it doesn't seem like it should. Appropriately gross, however.
This is a funny shot but not done well. You cut out the background and the feathering of the cut came thru, making it kinda glow but not in a good way.
IMO, the glow adds to this shot, increasing the puke factor. It wasn't enough, however, to make me enjoy looking at implied puke. Sorry. 4 (Lack of appeal)
