Hi Dak,
That's nice! I have done a lot of Celtic and ribbon engraving in my previous incarnation as a jewelery engraver. It is kind of tough to get the ribbon and Celtic patterns to look OK. You did a nice job. Congrats!
Looks nice Dak, but I see at least one area that you shaded in a way it can't be. So sort of optical illusion. It is the turn on the 7 hour. It makes a sort of "twist" there
The outside becomes the inside before making the turn!
