What a wonderful idea! I love the originality, and the title just made me laugh. I love the perspective that you used, and the bright contrast of the red shirts with a background of more muted colors. Its such a touristy thing to do.
Also, wonderful little details keep catching my eye-such as the eyes in the window, the frying pan, the clips in the girl's hair (she has a -perfect- expression too, btw), the levels of the city...and is that a broom I see in one dwarf's hand...?
