Bert, the Ram's head was made by cutting through the deck and fitting in the walnut, but it wasn't always a perfect fit. When I clear epoxied over it the epoxy filled the voids along the edge of the head and deck making it look like a black line. But if you put a light under the deck at night you can see light shinning through the filled clear epoxy voids. But the epoxy looks black because it is dark inside the haul. I can't picture if it would work the same way on yours since your inlay doesn't entend through your deck. But maybe you could take a black pen and mark the edge of your cutout in your deck so the edge of your inlay would look black where it didn't exactly match after the epoxy was applied.
