For example, with the additional art assets you've procured, a player could choose between Giant Snake, Giant Scorpion (both shown by Chambara), Brown Bear, and Snow Tiger (as just an example).
If you develop further, you could also have a list of attribute enhancements such as you did with Mesphit's demon form.
For that matter, I would love to see more done with Necromancy as well (and yes, some of it is being a fan of Chambara as well). For example, if you make a system in place for summoning minions, maybe a Necromancer could summon a Skeleton/Zombie.
Of course, a suitable thematic expansion of death-motif magic would be awesome. One could almost imagine bone armor, supporting Chambara's magnificent...frame
