First movement: the chromatic bits in the right & left hand are just fine, it doesn't let me relax too much in the beautifulness of the tonality, and somehow reminds me to enjoy its stability, as that could disappear anytime.
Second movement: It's even more animated than the first, I must say that's strange on you from what I've listened to (perhaps I'll get a better picture when I finish listening to all sonatinas), but I'm not complaining at all!
Third movement: Oh I just realised, 4 movements this time? This sonatina is full of surprises. This one is precious, the most lyrical of them at least for now (I'm about to enter in the fourth one).
Fourth movement: as lyrical as the third in my opinion. I didn't expect the ending nor the key. What a good sonatina you made!
