Stewart, there's definite improvement in your Melodia de Sor. Transitions are much smoother now. Good job!
The renaissance piece is coming along nicely. More smoothness would be desirable, but I'm sure that's partly the recording nerves. Although ideally the tempo should be a bit livelier, it doesn't sound bad at that speed, and should be perfect for ironing out the difficult parts.
Rick, you're making good progress with the Allegretto. The boxed sections still need work. The pull-off sequence is especially difficult (and doubly so when recording), and I think you muted the open 1st string in several occasions. I often repeat the 3 first bars of the 4th section over and over again, but I suspect that when it's time to record I'll mess up the pull-off's just as well.
A small memorization error: The 2nd full measure of the last section, the 3rd melody note should be 'b', but I think you played it as 'e'.
Finally something in nit-picking category: The study is in the key of E major, not E minor as your youtube video title (and in-video caption) says
