Christina's World, by Andrew Wyeth (1948) is one of my favorite paintings. I think of it most after I've spent time at home because for some reason it reminds me of myself, and the place I grew up. Although the painting has a rather forlorn feeling, it also seems wistful to me. I imagine that she is looking towards the house dreaming and wishing for something.
Many of Andrew Wyeth's paintings have this same feeling of isolation, which sometimes makes me sad. But I love the textures he develops in his paintings and I have especially admired how he captures trees. Each one has a distinct personality and he brings it out with what seems like extreme detail. I look to his work as a source of inspiration.
