Here's a preview of Over the Surface chapter 2, page 3!
Oh man, I have had such a hard time with the planes. Even if I had experience with drawing machines, brush pens are not ideal for straight or controlled lines. Lets just say that those planes in panel 1 did not start out as black silhouettes. :P
Still, I am really excited because I see a big improvement in my ability to draw cities and landscapes. When I think about how challenging panel 2 would have been for me a year or two ago, it's a good feeling. You've gotta dive into subjects you're bad at...it may be painful for a while, but it's the fastest way to learn.
