Hi Jonathan,
I really enjoyed listening to your second Sonatina. The energy in Movement 1 is really awesome.

The idiom is original, the modulations catchy, and the wild rhythms IMO a bit Kapustin-esque

It's waking me up after hearing the mostly lento music of Mompou in his 2nd book of Musica Callanda that Monica has posted! You play these superbly, I can't think of anything to criticise in the performance, and I'm trying to think of things...

Your new piano sounds very nice here. The string sound and acoustic setup is quite appealing to me.
I agree with Heather, I think a repeat of the A section isn't necessary.
I think a contrasting section in the Final Mvt. would be good. Starting at m. 9, I was expecting to hear a big minor section, so I was totally thrown off by the f # major return I thought I was going to hear f # minor and c # major. But as you have it now it's quirky, like Satie. I think you and I both like him

One suggestion about the score. The left hand of measure nine, you might see if your composition software can write 8vb lines, as it may be hard to read as it is written (what I learned was the rule is after 3 ledger lines, write 8vb).
The middle Mvt. I liked a lot with its curt bachian cadences and tricky quarter note burrowed division that I haven't really heard at all in modern music. In the beginning of the third intermezzo of Strueff's is one example I can think of off the top of my head.
Enjoyed these a lot, and think that they would be great to go up on the site.
