The worst part about P.o.t.S style is that people seem to think they can just take the aesthetics and just wing it. Phantom.of.the.Server did a lot of research and actually played a lot of games to get his signature style down. Each character had their own characteristics from their respective series. Nakoruru included some material from Samurai Shodown, yet still played in a standard Capcom style; Guy included elements from Final Fight; Dan had some of his more comical moves from the VS. series and parodied fighting games he hadn't before, such as Mortal Kombat; Geese had some elements from Fatal Fury if I recall correctly.
What I'm getting at is that custom things, custom gameplay is fine (I love Warusaki3's Jill and Captain Commando to death), but you can't just make things up the entire time and expect everyone to like it. You have to have the essence of the character in there. The most basic example, Ryu, should feel like Ryu, whether he's Capcom, SNK, evil, or slightly pissed off.
You may get a lot of "nice char +1" and "another pots style character, awesome," but these people will NOT give you any valuable feedback. In fact, most valuable feedback doesn't come about these days because of numerous reasons (mostly being that those who have been known to give the best feedback are busy with their lives these days, or have had their advice ignored so much that they've just given up with trying to educate).
Research the character, try actually playing with them for a while, get used to how they feel, KNOW how they should feel. Become acquainted with their design, both in gameplay and personality. That's what made Phantom's stuff so great and why 90% of others who attempt the style make things that feel like soulless bootlegs, trying to bank on what's popular.
Most importantly, if you really want to be like Phantom.of.the.Server, you need to innovate. That may sound hard in something that seems so limited and that everything's been done before, but there are still some things that could be solved, new things to try out, and new solutions to old problems.
This guy gets it.
