This reminds me of one of those ads you would stereotypically see at the end of a comic book. "Send $5 to us and we will teach you how to become a muscle-man in one week!" I especially like the negative space aspect to this image. There isn't much that actually defines the shape of the man, and yet he is still quite easy to see. I added colour to this, because it just felt better.
