Have you tried Live3D, Toonboom, Adobe Effects or any form of animation? It doesn't have to be frame by frame animation, merely squash & stretch and keybones so you don't waste time and if you do ever come across someone you can pay him $50 to "animate" 10 characters. That's how much I'd personally pay someone to just move some keybones around for me and I still consider that expensive.
So far unfortunately the best way to garner attention is to use copyrighted characters in your posts & everything and either say it's a work of parody(if you're American) or name them "Samus, Peach, Sakura, Rei, Asuka" only in the thread, but in the game the player has to manually modify their names to match. Then there's of course managing to make a web version and release it on Newgrounds and make some videos yourself and post on Redtube. The idea being to make each video separate with their own eye-catching titles, the titles can be fake as hell and even if the game says "Asuka" you can say it's what the player named her.
I like the way you streamlined and think, you're already very efficient at not overworking, I'm also a fan of the artwork even if the facial features and boobs are kinda samey. Give me a message if you'd like, we can discuss more especially on how to deliver more content without working yourself to death.
