Cut or wait?

For a start the sensor on the bud is making my eye twitch. Don't let anything touch your flower. Trichomes are sticky and brittle and contain everything we grow the plant for. You want them in tact and on the bud, not your sensor or fingers. To your question, yes, it looks like you are pretty much done. You could wait a few days, but I wouldn't leave her for more than another week at most.
