Im gonna try to create a website with tutorials on how I create my work soon. I try to use 1, 2 and 3 point perspectives. I learned from Feng Zhu's concept art videos and in my illustration classes. But its pretty simple, you just have to break the complex things you see on the paper into sections and simplify where the lines are going. Just start creating simple boxes in 1 pt perspective and just slowly build up from there.
