I see you edited to lance but didn't edit his role from swordsman. The only real issue I would have is mythical zoans are very powerful. I'm aware you already restricted his full transformation likely for just this reason but I still believe the half form as you have described it is too powerful for where most of us are at. I don't want to be too restrictive but I feel a quarter form might be best. Perhaps you should look at other characters and see if that feels appropriate.
