Here are my comments on your three pieces.
m.6: first note on third beat should be G
m.14: pay attention to the damping/rests of the bass note
overall: you've play this piece very rubato (just like professor Delcamp); one could argue that this exercise is about playing 4 groups of sixteenth notes right on the beat, which is considerably more difficult.
Very musically played! M.53-56 and m.61-64 came out perfectly.
My only comment is that the up-beat notes A and B in m.1-6 come out better if the bass note is damped (just like is indicated).
A funny thing is that I thought you made a mistake in m.14 and m.15, but it's me who played B (in stead of B flat) in the bassnotes of m.14 and F (instead of E) as last uppernote in m.15.
Thanks for pointing this out by playing it the right way!
