Really heavy on the treble in your snare and snap. I had to turn down the volume a little. I'd recommend either turning them down some or rolling off a little highs strategically.
This track has a nice vibe. It sounds like you might be clipping in places. If you don't know what that is, look it up. Best practice is to mix quiet, then let mastering FX or a third party online master handle making everything loud.
Your cello is also a bit loud relative to the rest of the track and sounds a bit dry. Chorus, reverb, delay, and panning/tremelo panning are all things you could do to liven it up. Another cello perhaps doubling the same line would also be interesting to hear, and perhaps apply all those effects on a send track for them both. Pocket Blakus is a good free kontakt cello, if you don't have it.
But beyond any technical mumbo jumbo, this is real smooth!
