I really like the first piece “I don't know”. It is very meditative and calm. You can feel the improvisational nature. The phrase at 1:10...., is good, those parallel notes are original, the only thing is that at the end, rhythmically it goes a bit out of the general mood of the piece.
The second “I got it wrong” is in the same line. Very nice part from 00:30 that sounds very delicate.
I think you do well to bring these improvisations forward. Maybe they will evolve in the future some pairs into something else, but if not, they are also fine as they are.
Writing music helps me a lot of times.
Best regards.
