Okay, Okay! That wasn't too bad. It kinda needs work though. The begining kinda was... eh. The song kind of got off too. Just keep practicing.
It really didn't sound like Wii Sports, however it does sound like a good Wii theme, it just wasn't Wii Sports, this is still very good though.
It wasn't perfect but it sounded kinda... Nostalgic, lol I dunno. *thumbs up* still good, though.
Please contact me if you would like to use this in a project. We can discuss the details.
