please don be disheartened, to me it sounds harmonically fluent and developed. personally i tend to enjoy a music if it sounds nice, regardless of its flaws in presentation. being an amateur myself i cannot promptly detect such flaws and therefore do not feel any repulsion or the need to express any unhelpful discontent just to assert superiority when i come across them.
in my opinion it has a simplistic but solid and inspired theme which lent well to the developments like variations and counterpoints, unlike some of the music here which only aim at a stylistic goal. (i don mean to judge the pieces with improvisation all over the place just to score some anachronism)
it has a calm and patient quality but i think it is too musical and creative to be ambience music. (not to disparage that genre)
