No.
Octopath which was the last big JRPG with a similar battlesystem as those sprites are intented for did not have animated enemy battler sprites, so I don't think it is necessary for this assetpack.

Although they didn't have any active animations, most enemies did have some form of idle animation.
Argument aside, are you planning on creating any additional 'player' sprites to go with this aesthetic in the future? I know you have the RPG Character Template, but I was curious whether any other expansions or updates are planned.
Actually I just recently created this set and the villager set as add-ons for the 50 monsters set.
Since those monsters/characters are designed more for a frontal battlesystem which usually doesn't feature player sprites, I could imagine that at some point in the future a good enhancement for this series would be sideview frames for the sprites to build something like a Final Fantasy II / IV / Octopath battlesystem.
Recently I have been significantly enhancing the GUI series. Generally I am taking requests into account, but since the assetstore is a sparetime project next to fulltime work.
