Hmm don't see a problem with the Batsi, why don't you show me your edit of it than i'll understand better.
Don't think i'd be a good idea to lower the head anymore for the Batso creature because it would just look flat then, i believe this is the perfect look for it, but of coarse you guys can edit that however you like for your game.
Forgot to add, i'm switching over to RM2003 and for a very good reason, i wish to work smaller since i'm working on original material and don't have a lot of time on my hands, plus using smaller character sets on rmxp and vx does not look good and does not work well imo, nothing will change when it comes to making monsters so no problem there.
