Looks good. As an FYI, I think the wedges in the through tenons are typically rotated 90 degrees to what you have there. I know of two reasons for this:
#1: When the wedges are hammered in, the force exerted by the wedges can split the wood if the wedge runs along the grain lines. It looks like you are okay here since it doesn't look like anything split.
#2: Wood tends to expand/contract across the grain. This could result in the joint loosening by some small amount as the wood expands.
I doubt it is a big deal either way, but I did the same thing on a previous project, so I figured I would pass the info along.
