Your art is fantastic, but the battlers just don't fit with this pack and feel thrown in there. 

Would love to see more attention put towards additional character animations, removing some of the duplicate items (for example InteriorB, InteriorB2, InteriorC, InteriorC2, all have the same colored sword, guitar, vases, etc.) Those should be moved to their own sheet then create alternate sheets for just the things that actually change. This would help with organization and performance.

I really hope you continue building out this style.
