Never thought this thread would see the light of day again. :X
Pardon my absence of answer. My attention has been previously engaged for quite a while.
That is quite the trying question. To summarize the entirety of one's inspiration is no doubt an impossible task, but I'll try to list at least some pronounced sources. Below is a list of some of people who inspire me, whether it be in the form of aesthetics, world-crafting, music, or simply madness:
Edgar A. Poe
Lewis Carroll
Lawrence Yang
Edward Gorey
Emilie Autumn
Crab Scrambly
Aurelio Voltaire
Roman Dirge
Amanda Palmer
Jhonen Vasquez
Danny Elfman
Tim Burton
I have viewed the work of hundreds of different artists, and every time I find a piece I particularly enjoy, I study it and try to incorporate some of the intricacies into my own style.
