Been lurking around this project for a few weeks now, and I'm pretty impressed with what you've already pulled together for your first time. I thought I'd do my part and give some input.
I didn't notice any serious game-crashing problems, so most of this is just small things that I noticed in about a half hour of playing. It's totally up to you to decide what is a problem and what is intentional.
-Wait animation. It looks like the battle pose he does in the games, but to snap to that every time he stands still is unnatural.
-Side special. It kinda just pops out, but maybe a sound effect or start animation would fix that.
-In general, many moves don't have exceptional knockback. Not necessarily bad or good.
-His down smash is REALLY good for a kill
-Ragnarok would benefit from more ko power *if* the attacker lands it perfectly.
-Your up smash, Growth, might need redone graphically. Looks a little off, but I don't know if you can do much about that. It doesn't look bad in combat though
-Neutral special is a little slow to use, but I like how it can be cancelled instantly
-Dat scarf. I'm sure there is *some* kind of way to make it move, but you'd have to ask around
-Final smash. I forgot to look at it, but it's a placeholder anyway. I don't have any experience fiddling with this, but you could probably take a sprite from one of the games (Iris/Catastrophe
/Judgment/maybe even Odyssey) and integrate it into the attack.
