My teacher and friend, Jung told me that it's better to understand how to create a mattepainting because it'll be easier to go back and speedpaint without having trouble with lighting and perspective. I was watching Pirates of the Carribean this afternoon and somehow while I was creating a composition, it happened to turn out just like it. lol
P.S. I don't know if it's my monitor's calibration for my both my PC and Mac, but it seems a lot brighter on PC than Mac. The darks is totally washed out.
