Beautiful
It's really amazing how such a small piece of music can pack so much emotion. I must have listened to this 20 times or so already and I haven't yet gotten tired of it. Some beautiful playing with nice dynamic control, I feel an overall sense of relief with an underlying tone of sadness. Can't reallly put in words, but you really constructed the chords well to generate some emotion. I also like the bassline and rhodes in the second half, and the addition of the subtle strings really helps to highlight the moods.
For advice, well I think many directions can be built from this little excerpt you have here. Maybe rest your right hand for a while, let the left hand arpeggios roll by for a few bars solo, and then bring a new lead melody on a different instrument like a soothing woodwind such as an oboe. Then you can use the higher registers on the piano to play chords every four bars or something. I would certainly make the strings more apparent and louder, and possibly thicken them up by spreading out the voices and building sustained chords to work as the background layer. Some ambience such as rainfall may help with the scenery, if that's what your going for. Maybe even a slow beat on some drums like hand or ethnic percussion would sound good in here, but it could possibly ruin the mood that you established in the beginning. Just a few suggestions, depends on where you want to go with this. I do believe this has the potential to be a very powerful piece, so keep up the good work and keep me posted if you release a new one! Thanks for sharing with us.
