Agree that getting disinterested in your hobbies is a bit scary, but sometimes after a time of rest they come back. Or so I hope, because I don't want to lose interest in game making!
As for the assets: two questions, if possible:
1. Will the sideview sprites have the "Arabian" style recolors/edits same as the regular sprites? (Also those are excellent, using them in a game right now).
2. Have you considered having the heads and bodies separately somehow and an extra? Like a Photoshop file with different layers. I'd be willing to pay a bit more for that, it would make editing "new" characters as combinations of bodies and heads so much easier, since the process is so slow manually (at least when you're not an artist).
Good luck and great job, itching to get my hands on these!
