If Your Canvas Is Blank.....Fill It Up

I was watching a video recently where the artist took pictures of complicated pieces of machinery and then turned them into these awesome environment concepts. I saw this as a way to overcome that initial fear that comes with starting out a new painting with a completely blank canvas. I definitely wanted to try this out for myself, so I visited CG Textures and picked out a few machinery textures that I liked and started painting. Here is what I have come up with so far. The top one changed so much you would not even be able to tell what it was before but It definitely was less intimidating to start painting on top of another image rather than just a completely blank canvas.
