Hey there,
Just to give you my personal opinion, I am looking for a sprite base and yours is some of the best offers out there, but there are a few points I'd like to point out, as to maybe add and improve to your services in the future.
1. The sprites are lacking a simpler loop, if I try to edit and shorten the animation to 3-4 frames and noticed that they didn't quite loop well, which means that I'd either have to rely on you for additional clothing, which there is no current option to as of yet, or create outfits for 12 frames of each direction, for each animation.
2. Animations, this is fine for town NPCs but that's about it, the characters don't seem to have other animations other than idle/walk/run, which is a shame because of what I mentioned previously and the time it would take a paying customer to fix this, which is the reason people pay for assets instead of making them.
Thank you dearly for your work, I hope to see you grow and put more content out there ❤️
