This is great! Are Dali and Miro artists you like? This drawing also reminds me of Bosch's "Garden of Earthly Delights" (http://upload.wikimedia.org/wikipedia/commons/thumb/6/6d/The_Garden_of_Earthly_Delights_by_Bosch_High_Resolution.jpg/500px-The_Garden_of_Earthly_Delights_by_Bosch_High_Resolution.jpg)
However, I prefer the way you keep your lines clear and defined and your tones monochromatic.
