More Concept Art From Tim Burton's Alice In Wonderland?

Russian film site has gotten their hands on what appears to be new concept art from Tim Burton's 3D adaptation of Alice in Wonderland. The initials on the bottom of that art reads "JM", and the only crew members with those initials are the set designer Jeff Markwith or lead model maker Jason Mahakian. The art isn't as Burton-styled as the previous pieces I've seen, so I'm not sure if these are legit or not.
