The Black Walnut just has the edge on the pair for me. Have you used a beading tool or rolled freehand.
First picture of the Cherry shows across the rim that you had movement, it's a large piece to have got stable, 5/8th is a fair amount, it's not a thin piece.
I like the plain and simple floral pyrography, it's far form being bold as with some work we see.
