Like many of you, I just got my Monster Manual today. I skimmed through it for about ten minutes and was pleasantly surprised - I knew reviews were good, but it was even better than expected. Anyhow, one thing that struck me is that the art was not only very good, but also very dynamic. I feel that many pieces were exemplary of the monster, and a few actually changed my view on a creature, brought it to new life. Two that come to mind are the cockatrice and merrow. I mean, damn. The cockatrice is so...visceral, and the merrow so damn cool. There are others, but those two stood out in particular.
What about you? What monster pictures stand out, even changed your view on that monster?
