I was about to use the UA weapons but realized ALL you posted doesn't have a black outline. It the tedious part of the job I guess. Maybe Alesprite has an auto outline feature?
Edit: Also, the UA art is too big and doesn't have a clear progression(small, medium, large damage, etc) with the blade types. And I have only been using 2 colors for the ore. They look good but kinda too fancy/detailed. They shouldn't bee any bigger than the daggers, I think.
