A pat on the back tells you you’ve done well in the past, criticism lays out what you need to do well in the future.
With that in mind - I’m not seeing your climbing line being utilized for much more than a butt weight. Draping your climbing line around the trunk in the first 3 shots is better than nothing, but I would have like to have seen you tied in. Could you have found a crotch in a nearby tree to drop your line in? Or climb to the top of that broken stub, flush cut the defect out of it, then carve a well rounded, vertical notch across the center. Drop your line into this for an attachment point. Oh, and you need to stand higher in your work. What I mean by this is your saw is at shoulder height not allowing you full range of motion. If you took a half of a step up to make that cut with your saw about even with your midriff, you’ll have better control over it and be less fatigued by day’s end - nothing’s written that you have to cut a limb off from just one position.
As for the 75’ Ash, I’m going to estimate you’ve trimmed the lower limbs as you ascended. I’m basing this on the angle of your stubs (you’ll stop leaving these after you catch a couple in the chest or hang a ‘hitch on them a few times…) shows they were cut at or even with your shoulders. Also, if you had climbed to the top to crotch in, I believe you would have tied a tipline while you were there to assist in what looks to be a butt hitch you’re now tying. You should really climb to the top of the tree, install your line and then descend, working the tree from the bottom up. It sounds like a lot of effort but your risk of cutting yourself out of the tree is greatly reduced. Think about the time it’ll take to haul your crumpled body to the hospital and compare that to what it takes to be tied in properly. I know a climber (maybe I should call him a “faller”) out in Western New York who’s cut himself out of a tree 5 times by working off just his lanyard.
