I love what you did with this tune, structuring it as Swing Two-Four and starting the head with a G pedal point. Rhythmic variation adds a lot to the tune. It's too bad there's no such thing as a double Coda so you wouldn't have to write the whole head out again.
The chord extensions were a little hard to read, overlapping the bar lines and each other. I took out the unnecessary 7ths, since they're understood in dominant 7th and half-diminished 7th chords, which freed up a lot of space to spread things out more.
