I just use a standard PC keyboard.

And I'm probably the wrong person to ask about execution. Those videos are highly choreographed—I basically mess around in training until I find a combo that I think will look good, and then essentially hardcode some (or all) of the combo into the character so I can have it done consistently (this is to make recording easier, I can focus on getting the perfect shot). And heck, this specific B.B. Hood combo is something I couldn't personally perform in the first place (that 3x crouch LK link into crouch MP is just too much for me, and it specifically has to be linked because if you chain into crouch MP you can't cancel out of it), so don't put too much faith in those combo videos!

Like they say, learn to walk before you run.
Take your time to read the documents that comes with mugen to understand the basics, start by editing KFM, learn what each sctrl does (they are already pretty easy to understand and self explanatory). As I said in my other post, there are plenty of tutorials here and on youtube (for general characters), you just need to use that and convert to the style you want.
About your fear of being criticized, this is unavoidable. The moment you put something out on the internet, you're subject to criticism. But that's not a bad thing, as you can LEARN from your mistakes, and make your characters better. Of course it's up to you how you'll accept it. No one was born with knowledge, we get it with dedication over time.

In fact, Shirtless Geese exists, full sheet by Dampir. Chuchoryu did a version too, but even the work is VERY good, it lacks sprites.

Even in a completely unrelated topic you're gonna beg for somebody to make content for you? C'mon man.

Hello.

A new variation is coming: Vega.



It is a variation of the animation made by Chuchoryu:



I made some changes on the face and the cap.
