The mountains are from a brush pack I found on this site (i *think* they were these ones..)
The trees are from a variety of nature brush packs (I got a cd from a friend with about 700 megs worth of brushes - no mountains though!!)
The whirlpool is from a japanese ukiyo-e (sp?) painting of an area of rough sea (found it on google, after slogging through about 40 pages of whirlpool brand dishwasher picutres, heh)
The rest of the art is my own original work.
And overlaying the entire image to bring a consistency in texture and tint, there's 2 parchment textures I created from half a dozen other paper textures.
