Great job!
I. It's sweet and beautiful. I particularly like the giocoso section. Bar 24 feels a little awkward. It's quite an abrupt modulation even though it is only from the dominant to the tonic.
II. It's nice as well. I think the left hand is a little unbalanced on the audio but that isn't your fault. I think this one needs a little more work harmonically, some of the progressions don't quite work.
III. A fun piece! I like the three bar phrases which give it a cheeky feel. The first section seems to close very suddenly, and could maybe be extended to sound more natural.
IV. I really like this one. It has a lot more depth. Bar 18 and 19 are a bit confused and don't really prepare for the recapitulation.
V. The first half is lovely. It does sound like a cross between a religious hymn and a concert piece. The second half needs a bit of polishing. It does technically start on the wrong beat. There should be a quaver upbeat rather than a crotchet upbeat. I think the changing harmonies need a bit more grounding. Introducing another voice could help.
VI. It's a nice piece, but I think your counterpoint needs some work. I can't give advice, because I am also bad at it. Bar 13-14 sounds a little bit off.
VII. Some of the rhythms are quite confusing. A live pianist with subtle variations of touch and dynamics would probably help ease this problem. It sounds a bit like a humoresque.
VIII. The theme is great! The first episode possibly needs a little work. I love the Eb in Bar 45 - it's a great touch. I am longing for it to go on a bit longer. It seems quite short and classical rondos are often very long.
IX. It's a wonderfully peaceful theme. I think the alto and tenor voices need a bit more movement in them. Some faster notes would increase the depth of it.
X. By far the most accomplished piece in this album. It sounds great. Some of the metric changes make it seem a bit unstable in places, and I think there could be some more development of themes overall.
You have written a wonderful collection here. I think some of the pieces could do with a bit more emotional scope, but well done!
