Nice install!For future box building endeavors, its best to brace across the walls, not just at the joints, if your box flexes, it will be centered in the middle of open walls, not at the joints were naturally it has the greatest stregth.

That is exactly right. I hear alot of people swear by those little corner triangle braces. But the reality is the vast majority of flex on your enclosure will be at the centers of the walls, not down at the corners. The corners are already the strongest part of the enclosure by far, and if glue and the proper screws were used, those triangle do little to nothing to help. Just run a 2x2 across from center to center of your biggest walls (if needed). Two of those 2x2's properly mounted would brace a box better than 100+ triangles would.
