Looks good, Greg!
I didn't have the patience for the Benedetto style kerf sections added to side braces , and they don't work out quite the same with reverse kerfing that I use. You have done a nice neat job of it.
I don't know if it matters, but I've tried to avoid sharp edges inside the box, so I round off the sharp interior corners of the neck and tail block, and soften the edges of the side braces. What do you think?
