Pick a book (fiction being preferable) and draw an environment from it.
(eg. The Lord of the Rings -> Rivendell or Harry Potter -> Dumbledore's office)
There can be characters in it if you like, but they should be secondary to their surroundings.
Don't be afraid to use films or existing illustrations etc. for reference and inspiration, but try to make it your own vision. (It would also be cool if you did use any sort of reference to feature it in your submission post!)
Deadline for this one is May 22nd (roughly - we remain easy-going in regards to deadlines ^_^ )
