To be brutally honest, I can't quite recommend this guide to people. It's very bare bones, only giving a brief overview of the most basic applications of each move, not necessarily stating how or how much it should be used. You should list some applications or your thoughts on each move at least, otherwise Ness players reading this guide won't know which moves are the best to be using.
You also fail to give a general strategic game plan for Ness, other than saying he's a mid-range character and to punish things. I actually disagree with the whole mid-range thing personally, as Ness needs to be close to exploit his powerful grab and combo game, and punishment isn't really a strategy, more like something all characters must capitalize on.
In addition to this, a lot of the combos you listed aren't combos, nor do they even really work in optimal situations against good players. Almost all of those dtilt combos won't work, as dtilt doesn't even properly combo into itself (which is bull****). Fair, DJ, bair shouldn't work in most situations either.
Sorry, but this isn't me just saying "it sucks," I'm actually giving you my critical thoughts here.
