It is hard to convey distinct emotion in monsters, but I saw this photo of a diorama recently that did a very good job. Despite the fact that these are "real animals" represented, I think my use here is justified.
Also, I have been impressed with art in the Kill All Monsters webcomic. Heck, the webcomic in general. They appear to have a published form for sale, but at the moment I am broke. And truth be told, I try to restrain my whimsical purchases.
