that's wonderful progress! You look so much more relaxed and confident on the violin.
My one critique, since you invited, is that you're slowly working your way to the tip of the bow as your second piece progresses. You might get some better expression out of your pieces if you work in a bit more of the rest of your bow. Think about the piece and decide where you want your phrases to begin and end. At the end of a phrase, pick the bow up off the strings and start at the frog again.
Amazing progress, @ KindaScratchy ! As a beginner myself, I find this video pairing very inspiring.
The earlier piece demonstrates tight arms and a kind of constricted sound. The second video shows you playing very relaxed and comfortably, with great intonation and fiddle bounce. My teacher has been trying to get me to relax my wrists when playing, so maybe I'll try the hint you mention above of playing along with accompaniment tracks.
Thanks for posting the comparison videos!
