well there all in minors so ill defo have a listen
1. i can see why this is for a maths teacher, quite 'mathematical' sounding if you get me, intressting, and i especailyl enjoyed the end, the dissonance in the middle part contrasted well with the overal harmony, and yeh i liked this peice. 6.5/10
2. beautiful opening, it sounds slightly improvised to me (i know all music is improvised) what i mean is it could be more polished, and even for a prelude its short, not as good as your first but still a charming piece 6/10
3. this reminds me of one of rachmaninov's etude tableaux's, the seagulls i tihnk, overall again charming but nothing out of the ordinary, simplsitic yet potent at the same time, this is perhaps my favourite, nice one and keep it up. 7/10
