Opening is definitely peaceful and tranquil, easy on the ears, very listenable.
I like the little pitch bending happening too.
I love the transition at 1:28. It hits well. I feel like the the guitar at 1:38 could be more punchy in its dynamics. The composition is good enough that the dynamics are becoming apparent.
I think the chord progression gets a little repetitive after a while. I think I want more bass in this particularly.
Track 2:
Loving this. I feel like this is hitting the vibe more than the first track. I think the overtones in this track are cool but also maybe start to get a little harsh and muddy. Composition is cool. This track is definitely my favorite of the two.
Flute sounds a bit midi - I like to lower the attack on instruments like violin and flute when doing midi, and then play them by hand with velocity control, but also overlap the decay of the last note with the attack of the first. I've found this makes the most natural transition for a gradual transition. Heh, I used a real flute in mine and then later, used a virtual flute, so I guess you can tell me how well the technique works from an outsider perspective.
Great work though overall. Loved this one. :)
