War Horse thumbnails

I've begun to make imagery for War Horse by thumb nailing a cover. I like the motif of the barbed wire, especially because there's quite an emotive scene where war horse jumps over some.

I have a list of scenes I think have potential to be illustrated - one of which involves a German and a British soldier settling who gets to keep war horse so I did a really rough sketch of what it could look like. I know that to fit Folio Society's standards, the drawing will have to be incredibly tight.

I went the E.H Shepherd exhibition at the House of Illustration in London for inspiration before tackling the brief.
