just listened to the youtube video in the link. I like the ideas!

I did have a couple suggestions about the mix, I think the violin is getting a little buried, and the muffled piano might work better "sparkly" (for lack of a better term). Seems like there's some room in the higher frequency ranges you could use to let those speak more clearly. 

The other thing about the violin is that the ends of notes seem a little abrupt, consider either lengthening those notes and fading them out in your DAW or do some dynamic phrasing if you're writing out in staff notation. You could also fake this effect a little by using some heavy reverb, but yeah the ends of those lines is a little dry. 

That being said, really seems like you're hitting the ambient tone you're going for! 

I listened to it. Sounds like you put effort and thought. I played with the idea of expanding into something like this, never knew what to attach it to. Good jib and keep it up. The sound and all seemed fine and all around it was good. Maybe, and I'm only saying this becasue you requested feedback, the video that went with the music might have not been matched well. I could have seen that with maybe in a game like Fallout...walking along. or wandering in Icarus maybe. Mechanically, you are on the right track. 

Hi! I've listened to your track a few times, and I think the biggest area for improvement is the way the instruments interact dynamically.

What I mean is this: try dropping the solo part out for four bars at some point. Or do the same with the piano. When it comes back in, it'll have much more impact and create a stronger sense of movement for the listener. Right now, the texture stays at almost the same intensity throughout, which makes it feel a bit monotonous over time.

The lower violins also sound a little muddy to my ears. You could try shaping them with a series of crescendos followed by softer entries, almost like waves. That would give the arrangement more space to breathe.

As for the mix, I can only comment as a listener. I think the midrange could be brought forward a little, since it feels slightly recessed. Also, that reverberant "thump" every two bars is a really interesting element, but it doesn't stand out enough. I'd try bringing it forward a bit more, either by raising its level slightly or giving it a little more stereo width.
