This is my own process fir technical drawings, but mostly it goes well on anything I upload. All what I draw usually has a remake while I digitalize it. In this case as you may notice I again run out of page. For this I have laid the back design of the ship on paper and moved it around for latter reconstruction. This net of lines and shapes will guide my inking in the process for now.
Attention ship is totally random, no reference were used more than the images live in my mind from all those war games I played so much.

Soon be scrap
