@Little Prairie Girl -
Oooh, Thank you! I LOVE a waltz & this is really nice!
I'm not sure what you could possibly be unhappy with in the B part. I only heard like a 1 note glitch at approx 0:58 that disturbed your cadence a little.
You may feel like adding or tweaking a little something down the road after playing it a bit longer - only because that's just part of being creative.
Very enjoyable - give it a name!
EXCELLENT! It sounds like an old timey 1800's type waltz which is a good thing. Theres so much to like but I really like the descending slides youve put in. Congrats on getting the composer badge. Youre inspiring so drop in and post when you record new ones. Good stuff! I agree with mouse and like the choice of black and white for the video.
The thing that sticks out to me about the B part, and maybe this is the reason you don't especially like it either, is the cadence at 0:57. You're ending the phrase on a I chord, which sounds a bit too final and gives it a stop-start feeling. If you can end it on a V chord instead (perhaps change the A-D to F#-E?) it might flow better.
