Majeur Mélodique (unusual mode)

Hi all,
I proudly show you my latest experiment, mouahaha! (Mad scientist laugh!)
I used melodic major (C,D,E,F,G,Ab,Bb,C), which isn't used often! A good cadence in this mode is IVm-I... the third of IVm moving down to the 5th of I... (as Ab go to G in C).

SoundClick song info: Majeur Mélodique by Christian Comeau - I'm quite a beginner composer. Still, if you want to hear some new classical or non-orchestral things...
Score:

The C melodic major gives this piece an exotic texture as does the instrumentation, and I see you have used the IV (F) melodic major as well. It is quite enjoyable to listen to. The ending on IV is unusual but provides a final twist. I think it could be made longer as the ideas are good. A fine effort.
