Industrial Moontruck

Some sort of industrial moontruck, ballpoint pen on paper + photoshop paintover. I really want to improve my values and lighting this year, with overall light being better distributed. This time I wasn't fully satisfied with the lighting in the ballpoint original so I went for a quick Photoshop edit. Trying to put on paper what my art teacher taught me as a kid: "it is the shadows that bring out the light"
