One thing that's consistent with my work is the inclusion of many styles. I find that I admire a lot of artists who have a distinctive, instantly recognizable style -- bright colors with expressive brushwork, black and white impressionist ink drawings, saturated watercolors with whimsical patterns, etc. But when it comes to my own work, I feel like I'm limiting myself when I stick to a single medium or technique. These portraits were created over several years. Can you tell that they were all created by the same artist?
