Plants are looking really good. Plan on taking the best pics you can (nice and steady) this coming weekend and post them. The Sunset pic above is a bit too blurry to see the detail we need, but the others have been pretty good.
Now if you're getting very impatient and feel you have to cut something, please do not harvest the whole trees just yet. If you HAVE to cut something, start with just a few colas. You'll have to decide if you want to cut your most fat, ripest colas OR leave those on the plant and clip several smaller colas. This will give you a chance to try out your drying/curing process and give the rest of your plants a bit more time to finish maturing.
Assuming you'll be trimming your buds by yourself, you'll know in a couple weeks what a time consuming process it can be. So staggering you harvest may make it more manageable for you to dry, trim, clip and jar your buds. Just keep simple notes on each group you harvest regarding the date they're harvested, the plant type, and if you want to really learn something about the process, buy a simple thermometer/hygrometer for your drying area which allows you to know the 24 hour hi/low temp and humidity. I got one like this from Home Depot for around $10 -

You're doing great, rounding the final turn and heading down the stretch with the finish line in sight.
