Reference pics for Razorback illustrations

Thought I'd have a go at posing some of my Razorback characters and putting them in some scenery.  Poser's really improved the "toon rendering" tools since version 6.

Charley (the swimming character) is meant to have webbed feet, but I haven't yet found a way to "morph" a character's entire foot.

I recently read a Stephen King book called "The Wind Through the Keyhole", which included some black and white illustrations.  There were only about half a dozen illustrations in total - they were quite simple line drawings, and made me realise that illustrating a story doesn't require complicated pictures stuffed with scenery and characters - that it is possible to convey a lot with very little.
