Not bad, indeed. Sounds like you've learned a few things, and had some fun, even played some music with the Arietta. But, reading your message, I can't tell whether you plan to try for a second year, or if you've had enough?
I am keeping my eye out for a Key of D accordion and I suspect my Arietta will be my "campfire music instrument". You know the kind where you set it down to pick up the banjo and someone sets a beer on it.
With only a year of playing, I have a very long way to go. So, I am not in a big hurry but I still drool over some of the LA instruments.
