let's see.. to me, the whole scythe needs to be rotated along its axis so the big hurt-y spike faces down. In the middle-back area the staff needs to be beefed up just a bit.. because it feels too thin to me. And lastly, i know you wanted to use one model for both the attachment and item, but it should be easier if those are two models, so both can use their own stand anims, so people can easily swap between weapons, without setting up tags
those are just my thoughts about it, what do you think?
(oh and the wrap and texture usage is awesome :3)
