During 2008 i helped MPC and Yanick Bourgie out detailing a lot of the winter landscapes for the quidditch sequence. For the efficiency and quick way of turning the autumn cyclorama to winter i developed a set of custom brushes.
I also helped out with some set clean up and extensions, in this scene Dumbledore takes Harry to another world, distorting the whole environment as it twirls and. With this some env cleanup was required.
