More chord progressions!

Spent the good part of the evening figuring out interesting chord progressions for the monthly sax forum song. Although I'd already done this once, the last few days figuring out bass lines and just playing with chord progression on the keyboard has given me lots of new ideas.

The score on Wikifonia only provided a few chord changes, so it's good practice figuring out the secondary dominants, as well as figuring out that I actually like the vii - I progression alot :3

Next time I approach this, would be from an arrangement viewpoint. Sax as lead of course, but which other virtual instruments this time round? Mmmmm.... :3

EDIT: F7 in the image above is actually Adim. 
Edit 2: F7 is F7 :P
