I'm sure it has been said before, but I just have not had time to read every single post on this thread - it just boggles my mind that you are able to pull this much detail from a photo of an engraving! For example, the anchor and crown a few posts back - I would never have even seen that, let alone figure out what it was supposed to be. Also truly amazing is that this is from an engraving! I don't know what the medium was, but can you imagine the pain-staking hours necessary to to inscribe all those little, tiny lines? One also has to wonder what Payne (I assume this is from Payne's engraving) used for reference. Obviously he couldn't refer to a photo. Was the vessel in one place long enough for him to carry his tools to the dock and work on it there? Did he first make a pencil sketch - even that must have required an enormous amount of time to record that level of detail.
And then for you to interpret it so well and render it in 3D. My hat is off to you sir!
