elk3 shows an appealing transition at around 1:00, but something sounded wrong, i don't know precisely what

i guess that the bass line is somewhat weak, but the harmony itself is lovely. you might consider changing some things to the chords structure. i feel that this section would profit by showing a bolder voicing. other thing is that the left hand is nearly all built up through up-down-up-down-up-down motion, that turns somewhat predictable after some time. the overall is fine for me, i guess that the problem is just some polishment missing.
elk4 is strange, seems to be just a sketch. the beginning is wonderful, but after 0:16 the music becomes a mess

with no structure and drastic changes of mood with no noticeable link between the sections. the return of the opening theme at 1:26 has no effect at all for the overall cohesion after such dismantling.
