That looks nice, especially for being your first! Great job! I love your creativity. I like how you used a reference without directly copying. That’s the best way to do it. I recommend adding definition to the nose and lips and adding some texture to the hair. Adding some more, shading, highlights, and details might help. Keep practicing digitally and traditionally and I know you’ll improve. I can see your potential. I have a thread dedicated to art tips, so feel free to check it out if you want some more tips! You’re doing great! Don’t give up!
