If you want a good frame of reference, download Mungyodance 2 and compare it with some of the files in there. Find the closest difficulty that matches the step chart that you made. Since boss songs aren't allowed in the contest, make sure you don't make anything comparable to the songs in red.
Also, if you (or anyone else) wants a second opinion, feel free to
Mediafire me a link to it and I'll give it a whirl. I've pretty much been making nothing but pad charts as of late.
