I've begun to play with Art Trading Cards in a bigger way this semester - probably mostly because I have hours and hours between my classes, and not nearly (yet) enough homework to fill the time.
Below are some examples of the playing in oil pastel that I've done so far.
Its pretty fun so far. I've never worked with oil pastels before so its both challenging and freeing. I think my next bit of play may be with water color pencils which also look pretty darn interesting.
