I don't do portraits as part of my painting practice. Human portraiture requires a different kind of focus and doesn't really interest me as an artist, though I admire it when it's done really well. That said, I have done the occasional horse or dog portrait for special occasions/people. I even painted Zappa a couple of weeks after I lost him.
This is Carlos. The painting (more an illustration really) is teeny tiny, only 4" x 4", in acrylic on Stonehenge rag paper. Carlos was the first Australian Shepherd I bailed out of a shelter (in Bellingham, WA) and found a home for after adopting Zappa. Carl named him. Julian and Connie, who eventually adopted him from us, are snowbirds who gave a gentlemanly dog with a rough start a really good life. Carlos died last year when they were in Arizona. Connie is turning 80 this month and doesn't have very long to live herself, having just last week been diagnosed with a terminal illness.
On impulse I decided that Carlos and his precious Blue Boy, who he never went anywhere without, needed to be painted for Connie's birthday. It was a bittersweet painting experience and I could've kicked myself for not double checking the drawing before I started painting as the proportions aren't right. What else did I learn? That I really need to invest in a pair of reading glasses (!*&$?!#!). This photo is of Carlos and Zappa, two peas in a pod.
