I will always recommend Errant story when stuff like this comes up.

Elves, time monks, gunslingers and mages.

Basically a story about a young half elf mage (who thinks she is the only half elf in the world) who is falling magic school and decides to go out in the world and amass power enough to force her teachers to let her graduate.

It's whacky, gory, vulgar, funny, exiting and the art is (at least in the later half) really, really good.

It has a black and gray morality were the lead elf and human are both professional killers with hearts of gold.
