Looks damn fine to me. Sure you could clean up a few parts (top and bottom boards) but sandpaper is evil 🙂 and why I started using planes. The clock, the joints, miters are great. Be happy to put it on my mantle.

I like the roubo quote above “to make as perfectly as possible” or as I like to say “good enough”. Good enough is not slacking, its just as far as one can take a projection without diminishing returns. You can always do better next time I say.
