I love these minor pentatonic type Hendrix style licks where they just spin notes under your fingers. This is a great flowing lick that outlines the minor feel of this progression.
Remember the chords are just as if not more important than the melodies. There are some nice glissandos in this lick too, especially the slide from D up to E. The resolution is to the A note (the major 7th of Bb major 7th).
