[GG] English Cover Sketches? (Patreon)

Kickstarting the English book versions G&G  is taking shape in my head lately. Here are some first cover ideas. I'm not too sure about them - I really like the legs, but they seem more like novel covers and are maybe too flat in terms of color/shading?

First one is Piet, second Tim.

Faces would be good, but the right idea still has to strike me ....
