Very good. Now as a wood builder fanatic guy, I would recognize my own minor boo-boo: the small protuberance at the top of each brace/bracket would be too weak going cross-grain like that. Your model makes it even clearer because it shows the wood grain. In reality, if I built it, I would modify it a bit, fatten it up maybe. It could split even under construction, when I'm cutting the brace! (this has nothing to do with your model of course.)
