I thought this was a very EFFECTIVE piece. Thoughtfully constructed, and within the time allowed, varied and spot on as far as emotional/atmospheric tone.
The style reminded me of John Barry --say Out of Africa. Can't say this is particularly accurate, but just a subjective impression. The short melody really is a motif that might be used in film scoring---giving a great deal of flexibility to the composer while being just long enough to be memorable.
Great work.
