Neat idea. I'm glad people are messing around with other people's assets in order to create new stuff, as we have done with in-game assets for years now.
That being said, I'm noticing a certain similarity between the animations in your recent uploads. If I'm not mistaken, they are all essentially the same? I'm not sure that that's necessarily a bad thing (except insofar as I feel like that base animation set could use some further tweaking), but it almost feels like they should be in a Bundle together or linked or something, despite how different they otherwise are.
