Well-done work, I got a few of your asset packs and they are great quality.
To help prevent potential issues, I would suggest explaining the differences between the assets. For example, they differ in size, and therefore are not compatible with each other.
If somebody is looking to but another asset pack thinking that the clothing and size of characters are compatible/convertible or that it builds off of one or the other, they would find themselves quite disappointed, and potentially angry.
the animations are similar but slightly differ even though they look like they share the same size.
It would be good to advertise your other works in your assets, just make sure people understand they differ a little bit and don't carry over easily.
