Spoiler: My thoughts (click to see content)
Hi, I haven't posted in a while here in the forum but I have some things to say.
First of all I have a feeling of deja-vu of the forum trying to do a project together, and if I'm not wrong nothing came out of it. I'm not implying that there aren't community projects because there are.
This is a hobbie not a job, so if people want to move on to another thing they will leave at some point.
Don't compromise to revamp FULL chars alone, even less in SF3 style, I tried to do it and realized that it was too much and it was not worth it. The amount of time and dedication to create a char is just too much, let alone the amount of frames and how detailed CPS3 style is.
Aim just for few animations, you can do a set of animated stances of Darkstalkers chars in CPS3 style, teach your process and that would be ok.
Problems are that you will be working with designs that aren't yours (silly me saying that in a mugen forum), but you are aiming for something very polished and nothing can stop CAPCOM from doing that same idea and rendering what you did obsolete.
And it's not only the feeling that you aim to do something as "official" as possible and knowing that it's not still enough for the big companies, if you aim just for mugen you still would need an income for your work, you could open a Patreon and given the situation unless you do something really unique or +18 it wouldn't be enough for how taxing the project would be. Revamping the sprites of a game that already exists isn't that unique, given that Morrigan has already a stablished moveset and you won't change that. I personally would aim to mod CPS2/CPS3 roms to include new sprites rather than do it for mugen, if modding is possible.
You know my background, the things I have done, the projects I started and let die, the ones I finished and are either not being used or end up leaving me with an empty feeling, foolishly enough to believe I was doing something official or that couldn't be replaced... those are on me because these were my ideas, ideas that I let go but are similar to yours, SF3 full chars. Even then, the requests and commissions I did for people are the best things I ever did. (Luckily enough I still get commissions that give me the same ammount per payment of what I would receive monthly if I opened a Patreon, huge frames for animations. That and an academic project.)
All in all I'm not telling you to quit or to stop spriting, I'm just saying you that you shouldn't bite more than you can chew and less for free, unless you have a faster technique like rendering 3d models into sprites. As I said if you want to do only a set of DS-CPS3 stances that's ok. But if you want to do your own full char or full game aim for something original: your own OCs, story, universe, in CPS3 style if you want and people will follow you for that unique idea. Like perhaps an OC that could fit in DS/SF universe and then you expand on that.
This is only a hobbie, you are a great animator, give it a better use.
