When YouTube references for Fan Games that only one person will get cuz you told them

[Diddy]

Too many people are making SSB games these days (I know I sound like a hypocrite, since I work for Rumble....), but if you still want to make it, then go ahead. It'll be hard to do, so be prepared to learn coding (a VERY long a difficult process).

As for the crits:
The legs should be side by side, not positioned the way they are. One leg should be in back while the other is in front. Add shading to the back leg to make it apparent which one is in back. For the hair, it looks a little weird, since it's stuck tightly onto the ducks head. You could make it look like the hair comes out a little and puffs up or make it extend out a little over his bill (up to you. This may be your style, I don't know). You definitely need more shading, and I don't know if you even thought about that much.

Well, fix these and then you can get more crits, I suppose.
