well done
i think this particular chord progression tends to get used A LOT when trying to evoke emotional imagery - and for good reason. It makes layering harmonically interesting instruments very easy to do as it tends to allow sustained notes landing on places in the scale to be held that you normally wouldn't be able to pull off with a different set of chords.
The 'drums' were a nice touch. Timbali? I can never remember the names of all the flippin percussion pieces that are available to ones arsenal now that using foreign instruments sets has become so popular.
