Updated 5/20-- the colors got thrown off when I uploaded it (weird), but I'm slowly making progress. I'm not really sure if I'm going about this the best way-- I have a bazillion layers right now since there are so many shapes, and I'm organizing them so that certain colors peek through.
Can't wait to get the basic shapes laid down so I can tackle the train!
I love the angles in this old railroad ad, and I think it's simple enough to get a good feel for the tools without getting too frustrated that it's not identical to the original. I'm really hoping to eventually add some textures, but that might be a story for a later day.
