Very nice first track, good amount of reverb, at 1:01 we can even hear yourself adjusting the lyre XD but it adds a small sound design to the track probably unintentinal but its great. I like the different techniques you tried playing your made up instruments with a more melodic plucking and a more piercing/muted play later one.
Now the main issue is its too low in volume, I had to crank up 10db to have a decent listen and have a good idea of what I was listening.
Second track, I really like the overall vibe of this one, I can sense the emotion, I would say you probably put too much emotions that it seems like your playing is going all over the place at some point, I know you like those dissonance and it gives some very interesting intonation and weird chords, don,t know if it was all planned. But yeah the main issue would be either fix the strumming to be more precise or if you want to keep it organic take off the "percussive" elements there is some small tap on the lyre maybe in the low registrer announcing the rythm, take it off and it would probably make more sense.
Anyway always interesting to hear what instruments you came up with and how you make it sound, your tracks are always fun to discover with real instruments unlike mine which i'm starting slowly to incorporate more real instruments.
