That looks great! Only thing I would add is hurricane tie downs for the roof rafters as seen at link below.. I bought mine at HD I believe.. Simpson Strong-Tie 18-Gauge Hurricane Tie-H1 - The Home Depot
Great job, looks amazing. I just went out to bring some more wood up and there's so many leaves and crap in my stacks I think at least the first ten layers or so are way too wet to burn. I'm building something like this next year. I would like to use a very similar design, maybe around 32' long though. Thanks for posting, an inspiration and no doubt I'll be looking back at this when I build.
