Wakko's Patronus Charm by FerryQueen

This is a personal favorite of mine which never fails to make me laugh. A friend of mine drew it back in 2010, and combines J.K. Rowling Dementor from Harry Potter and Warner Bros. Wakko. Here, Wakko has conjured his Patronus. Most times, this would be an animal. In this case, Wakko's got a hammer, and the Dementor looks distinctly worried. The contrast between the bright blue and white at the center the darkness on the edges draws the eye to the center and then explores the corners. It's bright, its bubbly, and fun.

USAF Battleship Excalibur by Mallacore

This starship was designed from the Stargate intellectual franchise, by artist pen name Mallacore. I watched the Canadian/American TV series Stargate as a teenager and was entranced with its story and science fiction. The show hosted many different designs of starships, but my favorites were the ones designed for humans of Earth. Though the series has been discontinued, artists continue to surprise, as has Mallacore. This is the Battleship Excalibur, a 1 kilometer long vessel capable of enduring tons of punishment as well as dishing it out. The lines are smooth and utilitarian, but there is a sense of power and majesty in the Excalibur's bearing that appeals to me. A larger picture can be found on deviantart.com, here:
