I still make sprites, and I still enjoy making FFT sprites. I've just never had any particular interest in making Vincent's beast forms, even back in the day when I was keen on making all the FF7 sprites haha. I still occasionally load up my old FF7 sprites and make changes to them though, would love to finish them all some day. I made the Vincent Valentine sprite, so asking here for permission to modify parts would be a perfectly reasonable excuse to necrobump. It's all about context haha.
I don't post my work here anymore, I mainly do so on the FFH discord. I do take commissions though, so if you needed any fixes to anything or small edits I could help with that. A large MON sprite like Vincent's beast form would be a bit much.
I'd recommend taking a look at other SP2s on (the sheets that are longer than normal) to get a better understanding of how they work. It's an additional animation to give the monster a different looking attack. A lot of custom monsters don't have SP2s because they didn't really need them, and it was easier without them for reasons; We can't add SP2s to existing sprite slots, only replace them. So it was much easier at the time to simply make a MON sheet without SP2s so you could replace any sprite, whether it be human or monster, thus anyone could enjoy them!
Good luck with your mod
