I´ve always liked to do image retouching. Trying to visualise the impossible and trying to find new ways to do things. I´ve used matte painting, 3D models, Miniatures, cardboard cronIutouts, you name it.
I have also set my goal some time ago.
Some day I would like to do photography and retouching for movieposters, especially for Superhero/action movies. I know this is pretty out there, since there are only a handful of people getting these kind of big jobs, but you have to have dreams that push you better.
