My First Stepfile!

I finally managed to get Stepmania to work - not the one I downloaded but I bought a dance mat and Stepmania came with it. I tried editing some songs and so far this is the one I'm most pleased with:



The song's called "Chap Hop History" by 'Mr B. The Gentleman Rhymer' - it's a parody megamix of a load of old hip hop songs. Again, I've not asked permission for this song, so please don't take this as an actual submission - I just want to know if it'd hypothetically be considered good enough if I did have/get permission.

E: Sorry, forgot the mp3. Here it is, and the stepfile file too!





By the way just FYI - I'd probably rate the song around 30-40 difficulty (I play at between 30-60 difficulty myself...). Most of it is pretty easy but there's a couple of segments where I got a bit carried away. I'm fairly pleased with it (especially as it's practically my first attempt!) but I think there are a couple mistakes, especially the last 'riff' is a bit off...

(Also does anyone know how to use a dancemat?? It arrived last week but I've hardly touched it... it's so much harder than I thought it'd be. I bought it to get fit whilst playing rhythm games - and, I guess it'll do that job because I was out of breath on the easiest songs... Does anyone have any tips on how to play? I hadn't considered the fact that you don't have 4 legs, and you have to leave at least one leg on the ground most of the time whereas you can leave your fingers floating above the keys...)
