the quick sketch plugin is look very interesting. Is it possible to apply a finished sketch as a deformation to subdivided mesh.
Hello,
interesting question… i quickly tested it out and there seems to be no problem to apply it as deformation. Because u paint in a Grayscale u can apply it as diplacement map 
Its just the same workflow like the baking materials workshop in the zclassroom.
P.S.
I really like the models on your blog. Very cool works.
