I've made at least twenty stages, so I'll just post my favorites.
Sorry in advance for the poor picture quality, if anybody asks I'll upload any stage to IGN. I may add a few more later, but I just wanted to get some C&C for these ones.
1. Name: OoT Ganny Battle
Music: Ocarina of Time Medley
Picture:

It's supposed to resemble the battle between Link and Ganondorf in Ocarina of Time. The dropping blocks are supposed to be like the floor collapsing, and the springs are the wall climb. I tried numerous ways of setting up the lower area, but the open floor is the best way to keep the fighting in the upper level like I intended.
2. Mario Castle
Super Mario Bros. (Title/Ending)

This one was supposed to look like the castle and flag at the end of levels in Super Mario Bros. It's not that great, but I'm fixing it up so I'll keep updating the link.
3. Tower
Ridley Battle

I don't know about this one... I just made a pillar of ice and threw in a few dropping/moving platforms for fun. This one's good for stamina battles.
4. Base
Encounter

Another one I'm not sure of. You can rack up a lot of damage down in the lower areas. I put a little building-thing at each end of the "path".
5. Temple
Super Mario Bros. Underground Theme
http://i26.tinypic.com/2jepzdd.jpg
This stage is like a maze. Sort of. The upper area is best for heavy characters, seeing as they don't get knocked back far, while the "inside" is best for light characters with it's jumps and whatnot. I actually added a few more things, but I don't feel like getting a new picture. Fun with four players.
6. Arena
Pokemon Theme
http://i25.tinypic.com/o5oqat.jpg
I made this stage for "soccer" games with my friend. I made an original version that was bigger. The stairs at the tops are supposed to be stands, by the way. I used ice to keep the ball moving.
7. Item Factory
Go K.K. Rider
http://i27.tinypic.com/2psix45.jpg
This is my remake of the infamous CD/Sticker factory. This version is designed for two players, one at each corner. The only problem is that occasionally the sandbag will get caught in the middle of the lower area.
8. Smash Light
Final Destination
http://i26.tinypic.com/qsnzg1.jpg
I made three of these, Smash Light, Smash Heavy, and Smash, each specifically designed for a different weight group. This one turned out to be my favorite. I used ice for the top layers to make recovering harder. And in case you didn't notice, the main platform is in the shape of the Super Smash Bros. logo.
Oh, and thanks SL, I'm gonna get those stages on my Wii right now.
