Is this more concept art from Alice in Wonderland? The Russian film website filmz.ru has posted up these images, mostly of a fungal forest.
The initials "JM" appear at the bottom of these illustrations. If it is for Wonderland, then these might have been drawn by either lead model maker Jason Mahakian or set designer Jeff Markwith, as slashfilm suggests.
However, this is just a guess. We can't confirm if these images are actually official concept art for the 2010 film. Still, they're intriguing.
