You have a beautiful art print and are most assuredly talented, creative. I noticed that you have added strains of a teal in her latest color trend. In my humble opinion, it takes away from a real Gaga look. I would leave it in the green hue only more vivid. The black attire is perfect as it doesn't take away from her gorgeous face. I love your shading technique to highlight more depth. I would like to see more darker lips of a deeper red hue and a little more green in the iris. You can still maintain a soft look with addition of more color. Please, don't misunderstand me, you have a gorgeous art piece and is perfect the way that it is. To make it more Lady Gaga as I view her, I would do the suggestions from me. If you like it, leave it. It is your unique style. You are an artist, yes.
