A little to simple, to the point where your low end is kind of lost in the whole mix. 

I like the simple and minimalistic appoach. It fits the theme really well.
The low pitched chords are kinda hard to hear. Maybe try a more open kind of voicing.
But it's a really good start, good job.

I like the minimalist approach you took. The music is understated which can sometimes be far more effective than something overdone; less is more. The chords are quite low. You could try revoicing them (as mentioned in another comment), bringing the entire chord up an octave (which would be okay since the melody is so high), or even "flip" the registers of the melody and chords so the chords are higher than the melody.

Overall good job for a beginning attempt!

Okaay I like the simple approach, it works, its easy to listen to, since you are asking for feedback what I can tell is on the keys, stacked chords on the low registry especialy triads will always sound bad so the trick is to change the voicings example you were playing Bb minor chord  very low Bb - Db  - F, if you play it an octave higher with Bb then F and an octabe high Db you will spread your chord across the spectrum making it sound huuuuuge. Other tips, quantize your playing a little bit, we can feel some hesitation in the play, it sounds more organic but we can pinpoint more mistakes, quantize around 60 to 70% your MIDI and it will play on time but still feel human. Also  last time but its for itch.io , your daw screenshot you can just add it to your project page and it will  translate to the submission. well done !

I think this shows a lot of promise. Definitely room to grow but it's clear you have a good grasp on tension/resolution and I think theory will open a lot of doors for you to become more expressive. I definitely enjoyed listening and look forward to hearing what else you come up with in the future.

You did a pretty good job on this! It's a very interesting Piano Patch. As an Ambient Music Producer, I thought I'd give you the tip to use a lot of Pads, Textures, & Soundscapes to produce good Ambient Music! However, a Piano works just fine. Pianos are great in a way that they can be used in basically every Genre of music well. Hope you can get better with producing Music, if you enjoy it!
