I think it would be pretty neat if you had somewhat 3D models for the weapons and not just a sprite in your hand that looks like the item but isn't in your hand.
(not sure if you've done this yet I haven't downloaded the mod)
It would also be cool if you had it so if you do alchemy without anything to give you would lose a body part and that would be shown on your player-model and you either have to craft automail or find a shop and pay a NPC.
(you would get money from completing tasked the other NPC's asked you to do, or you could find a city and become a state alchemist. again not sure if you've done it but eh just my suggestions)
