Bea! I think you have improved very much during your absence!
Regarding your left hand pinky, the strength will come eventually as you progress with your playing. For keeping the pinky closer to strings, I think you just need to pay attention to it when you play, and in order to do that you need to practice slowly, much slower than the tempo you now played.
In general I think your left hand would benefit from practicing scales, more specifically the chromatic scale, which is exercise number 8 (page 74) in D02 collection. When you do that exercise, you should focus on these things:
- keeping the fingers not currently fretting a string only few millimeters (a couple of tenths of an inch) away from the string
- Ascending scale: when fretting the finger, keep the fingers already fretted on string (but ease off the pressure), for example when fretting the string with your second finger at second fret, ease of the pressure of the first finger slightly AFTER you have fretted the second finger, but do not lift the finger off the string.
- Descending scale: Initially you should have all the fingers on the string, and when moving to next note, at the same time when you lift the finger, for example pinky, (just a few millimeters ) off the string, just apply enough pressure for the next finger (the 3rd finger) so that there is no buzz.
Then you will need to translate that scale technique into the playing of the piece. For example in bar 18, you tend to fret your 2nd finger only after you have lifted your 3rd finger off the string, which will cause the notes to sound disjoint (not legato). You should have both the fingers on the string right at the beginning of that bar.
Another thing that caught my attention was the duration of the dotted quarter notes in the A major section of the piece. They should last as long as three 8th notes, but you played them short, lasting only two 8th notes, which causes the rhythm to go off.
You should also work on the bass strings damping with your right hand thumb where indicated in the music sheet. It's an important technique that you simply need to learn, although it will make the playing feel more difficult at first. It will become almost automatic soon though.
Otherwise good job!
