4 years in jazz ensemble and I can't do it...

I have composed a total of two pieces on paper. Both of them seem to fit in the Baroque and Neo-Classical genre. I had started another piece and stopped due to my teacher's sudden demand of a jazz or blues composition. I started and destroyed the whole thing today in a matter of fifteen minutes and realized I'm not getting much further than the left hand piano part. I, honestly, am quite stuck. The unfinished work has a heavy swing/ triplet feel that's rather undeniable at the moment; and the tempo coupled with the minor chords are definitely leaning towards a blues composition. The problem if I don't know where to go from my left hand piano part which boasts the e minor scale lovingly. Any suggestions?

Can you post a pdf/midifile/whatever of what you've done so far?

I'll see if I can have my teacher send it to me as a pdf. file tomorrow.
