Collaboration with Sander Jansen. He did the bottom half, covered it except for a one inch strip, then mailed it to me and I did the top. Check out his excellent work at [link]
thanks, yes, the contrast was quite effective in this case for sure. Glad you like it. For folks doing this types of semi blind collabs, they could learn a lot from Sander. The trick is to give information in the one inch strip that is visible and to keep the technique uniform throughout. This was an easy collab to do and quite enjoyable. As soon as I got it, I was ready to go.
thanks! I can only say that it was a one inch strip near the middle of the page. Basically, if you cut the drawing in half, Sander sent me the bottom half with the top one inch showing of the bottom half.
It would be really interesting to see what part of the image you were shown, a brilliant and amazingly detailed collaboration!
