Quasi, are you still looking for someone to help with the graphics? I mean, i could easily do some character animations based up on Ragnarok Online sprites for you, so you could retire the arrows.., I'll just need to know if your ABS supports multiframes or not and if don't, wich would be the animation play sequence.
To be honest, I'm not familiarized with Rpg Maker MV, nor the VX. I'm used to Rpg Maker XP.
By the way, did you ever take a look at XAS Hero ABS (Moghunter)? Not the one for VXAce, but the XP one (far more complete)? If i'm not mistaken, LiTTleDRAgo did some customizations with the system with a few add ons, wich turned out to be great. The name is "XAS - 3.91 Ally System v1.56". It's full of nice ideas, definitely worth a look.
EDIT1:
I could also TRY to make these character animations with the default RPG Maker MV RTP, but progress might be slow, since i only have very few hours (2-3).
- Hurt, Cast, Attack animations
Also, have you considered multiframes? More than the usual 3? Wich the play order is 12345x, not 31212?
