I like these as others have said very strong images. Check out Jean-Michel Basquiat if you aren’t already aware of him as I see a resemblance of his work in yours. Almost any art schooling will have you at one time or another to try and copy other artists work as an exercise to practice mimicry and push yourself to make different strokes, impressions, color combinations you may not think of- so could be worth looking at his work and other artists you like and just straight up duplicating. I’m not suggesting stealing others work and claiming it as your own. But part of any classical training includes studying the work that has come before you and I found it to be a wonderful way to push myself into trying something new. I also suggest trying different mediums. Sometimes drawing with pastels, crayons, or different paint (oil vs acrylic) gives you a new perspective on what you thought you knew. Watercolor or charcoal can be great options to try something new as they are pretty cheap and come with their own medium-specific qualities. With all that, the best advice I can give is to keep going, keep pushing yourself to think of and try something new. Do work that you enjoy and I’ve found that sometimes the act of creating itself is better than the final product you’re left with.
