I am a big Doctor Who fan (and Star Trek, and well, you know sci-fi in general, lol), so you'll see some TV related art from me from time to time. I wanted to do a simple "graphic art" piece, but not so... galactic?
I re-purposed a canvas that I botched (lol, I just didn't like how it turned out). It had a grey gesso base, which was perfect for this project. I used artist professional tape to block out my image and a Tardis blue spray paint to evenly coat the background. It took several coats, but I'm very happy with how well it turned out.
Next, after everything dried, I removed the tape and added details in with a white paint pen.
