Some issues related to battle animations:
#30 - Animation Speed. AFAIK, this should only impact the “active” animations. By that I’m referring to: attacking creature, retaliating/dying creature and spell casting/animation. It should not impact the “static” animations, aka what the other creatures are doing when it’s not their turn, nor are they subject to an enemy attack or friendly spell. The result now is that on “fast” some of these static animations become really hilarious. In the battle from the screenshot in my previous post for example, the flag of the Tent was really fluttering like mad, while the Titan looked like he was dancing or sth. 
#31 - Static animations. I am not sure here, but did you take the static animations you’re using from any of the Heroes 3 versions? I only have Heroes 3 Complete and WoG to check, but in those the static animations are totally different. In VCMI all creatures are continuously doing sth (e.g.: Cavalier’s horse is continuously ‘shaking’ his head and waving its tail - in a slightly unrealistic direction I might add). In H3C they are pretty much standing still, and only about every 10 seconds they have a custom, more ample animation (e.g.: Cavalier’s horse is lifting its head, and also the lance is lifted a bit, probably symbolizing the idea of ‘charge’).
#32 - Glowing effect. In H3C, when a creature has its turn, the yellow outline has a glowing effect.
#33 - Rough pixel change on static animations. The static animation mentioned at #31, combined with the non-glowing outline at #32, leads sometimes to noticeable ugly pixels (“ugly” is maybe too strong put, but it gives the feeling that the creature outline was done a bit roughly, that it’s missing a finishing touch or sth). The yellow outline only emphasizes the changes in creature shape due to the static animation. And that leads, in the case of (Ancient) Behemoth for example, to a group of pixels appearing/disappearing from his back whenever it “breaths” - as I assume that’s what the VCMI animation represents in this case. It’s not noticeable without the yellow outline, but once it’s Behemoth’s turn, you can easily see it on its shoulder.
