you should probably remove or actively seperate your stuff and the sheets you used as reference on that dump, and I'd recommend doing seperate sheets for your original works and your edits, quite alot of it is looking nice though, but as i said recognized other peoples work namely game sprites/sprite sheets.
I like your FFtactics Style uprez'd character looks quite appealing. also you should probably compile that animation sheet of yours and make it into an animated gif, most people aren't going to do that themselves, and can't easily crit you on it.
