Worrking from 'below the canopy of the umbrella' I would just take out any old, damaged or crossing branches, removing them from the centre of the canopy, and then I would remove the tips of any branches touching the ground. I would then stand back and identify any branches spoiling the outline or symmetry.
Apart from that I'd leave it alone.
