Here's the final line art for my Airship Refueling painting. Because the line art always looks so flat, it's always a pleasure to start applying color. The depth and dimension of the color always brings the image to life. You can see that I added the buildings in the bottom center. It was still in pencil in the last version. But I'm still up in the air about what will go onto the fuel tank, center left. It seems like there needs to be an appropriate name or graphic there. I still feel like Sub-Standard Oil is a little too tacky. Let me know soon if you have any brilliant ideas.
