You seem to have lost a lot of detail in the dark areas. I would recommend using the raster image after processing in Photoshop or other editor. This is a image I used on a cutting/cheese board.
It came out great. Adapted from: Aemilia, het vlaggenschip van Tromp, ca. 1639, Hugo Allard (I) (attributed to), after Willem van de Velde (I), 1639 - 1684
That is actually a raster image. I am trying a little more manipulation to clean it up a touch more without losing detail. There is a challenge in that Raster “white” does not equal Vector “white”.
I lost quite a bit time to these, (especially because it generates click-for-more listings instead of being paginated).
First engrave out of what I found so far was “The Seven Works of Charity” (Theodor de Bry, 1588).
