Precision work at its finest. I really think the attention to detail is superb. For example, the efforts you took to ensure the battens are bookmatched, also the grain matching / bookmatching of the panels, the allowances made for seasonal changes, the sliding dovetail batten fitting process, etc. I have no clue how you manage to create a tapered dovetail of only 1/64" over that span (I assume that both sides are tapered at 1/64", ie: not 1/64 total). Very well done.
