Great job on those, they look great. I will usually pull away any leaves that look COMPLETELY dead because they stop serving any purpose at that point. Do you have a magnifying glass? Look for some amber colored trichs and if you see some id say chop it down. I am at the exact same point as you with a few different plants and I am just taking the tops off of some that look done and letting the lower ones ripen up a bit more. After you cut em down, you are in for the hard part: drying and curing. Make sure to read the sticky post on harvest time:

patients is very key otherwise you'll end up with some nugs that smell like hay or grass clippings or something - its happened to me before and its really disappointing and frustrating so make sure to hang dry for about a week, no longer, then put into brown paper bags, opening them every once and a while to let the last bits of moisture get out of the buds. You could also use mason jars or something but if your harvest is big they might not get enough air in the middle. Remember, the only thing worse than having to look at bags and jars full of nugs that you have put months into growing and not smoking it is smoking it too early and being disappointed.
sorry if you knew all of that but i read somewhere that growing is the science and curing is the art, good luck!
