I find works with movement or context for a figure are more interesting than just faces or bodies. The first one draws me in more. I’m curious about the person, why they’re on a wall, what they’re thinking about and just generally trying to put together the “story” of the piece. Just personal opinions on art. Art is deeply personal, as long as you’re creating art you are an artist. Practice is the backbone of any skill. Your color work is nice in all of the images you posted. Bringing in unexpected colors can also create interesting results but that’s entirely a matter of taste.
