Here's a nice one I did for a teacher I work with, for she and her husband's anniversary. I also drew up a little 'character' version of her, below, which she hasn't seen, but I liked how it came out enough that I thought I'd share it here. Pitt brush pens and color sticks were used.
This was done for Campbell's Soup in Camden NJ, a long-time client, and I quite like how it came out.
Used Copic markers and color sticks on this.
