I tested the Skull Kid psa a little just for fun, and I would like to mention something that seems a little annoying according to me, it's a little thing but still I think it deserves to be mentioned.
When you use forward smash, sometimes, there is a giant but thin purple triangle that appears during very little time, I honestly don't know if it is a problem that I'm the only one to have, but if it can be fixed, I think it could be a good thing, if you know how to fix it of course, and the most important, when you have time. It's a detail, so if you want to focus much more on other things I would easily understand.
After that, I have nothing other to say, there is no other real problem, excepted with the shield but as I know what this thing is about the shield, I know it was done on purpose so I have nothing to report about it.
Anyway, good job, it is a sympathic Psa, but overpowered according to me. It's not a problem at all, you haven't stated if he was going to be overpowered or balanced so...
I've also had that problem, sometimes when I roll as well.
