"Working on this for a few weeks" blows me away. I've been working on this for over a year and I'm still not playing as well as you. After a "few weeks" I still would not have had the first movement memorized.
In the 2nd movement, you shift positions a lot; you might look into alternative fingerings to avoid a few shifts. At 4:11 you play a C on the 2nd string 13th fret, which seems awkward, although I like the tone. I play that bar in the first position, play a C on the 8th fret of the first string, and then return to the first position.
If Denis Azabagic was watching you play he'd tell you to bring your palm closer into the neck so that you're not stretching your pinky out so straight...
