I need cover art for an eBook. The book's title is "An Uncommon Vocabulary". It is an A to Z book of common words and phrases that are described in a manner better suited to them in the opinion of the author. In some respects, it is similar to the "Devil's Dictionary" by Ambrose Bierce.
Some ideas for the cover include: A nexus of words and phrases, a professor (not a real person) character with a blackboard, a speaker (penguin) at a podium with a board behind him, an abstract character pondering with a thought cloud above his head, a howling small dog, a textured book background with simple lettering and a fancy border (dark green with gold lettering and border). Some links to stock photos are incuded below, but the design should not include stock pictures,
