It can be really hard to make an interesting arrangement of an already well-orchestrated song, but I really like what you've done with this. The intro was especially cool, easily my favorite part. Loved all the sound effects thrown in there! Stellar stuff!
I grew up playing the Super Smash Bros. Everytime I think of it, this song gets me everytime. :)
Please contact me if you would like to use this in a project. We can discuss the details.
