Melodies with 2 chords exercise

chords: Cm – G
first one starting from the 6th
second one starting from the 2nd
third one starting from the 4th

2 questions:

I tried to start the melody when second chord would start with the equivalent intervals of the second chord, but still using the scale of C minor. Is that correct?

I was unsure if I should finish, or start with the interval used for each exercise in the second chord. I don’t play much melody everytime when the second chord plays because of this indecision.

being the 2 chords a bit slow paced, I felt like the need to put more notes, but tried to keep it simple
