Really enjoyed the vibes on all 3 tracks. I especially loved the sound of the flutes in the 1st and 3rd track, and the piano texture on the 2nd track.
A minor thing, but I think the brass rhythms in the 1st track clashes a bit too much with the piano and violin, and feels a bit out of place since they are not heard again in the 2nd and 3rd track. Brass sections tend to be very bright sounding and will draw listener attentions to them, which could overwhelm the other melodies if not mixed correctly. Maybe try swapping them with cello/violin staccato or pizzicato for the rhythms and see if you like it, but this is just my opinion.
Overall I think they are wonderfully done, and I look forward to hearing more of your work!
