Little Duet, Rondo

3rd part of an intended 4 movement piece. 

Charming.  This is by far my favorite out of the three movements you've posted so far.  I think the score you post is not complete though.

Quaint, and very interesting.

Some of your cello double stops (especially the 3rd's) are very difficult to reach out of nowhere. Be cautious of that. Also some of your intervals clash a little in areas where it seems like it's supposed to be tonal.

I do like how a lot of your modulations happen very quickly and without you noticing sometimes. Pretty cool stuff.

I like it. It got a kind of jazzy feel to it in the begging, and is just very fun and bouncy. It does start to get a bit bogged down around m65, and though it's understandable that this is feels a bit incomplete (being a single movement out of a group) the resolution does feel a little empty. And as @Monarcheon mentioned, there is some clashing tones in areas. Overall though very good.
