I don’t know if you want advice, or if I’m good enough to give you advice but I’ll try. Okay so first the BIG thing is shading. Take the skin color and go slightly darker. You could also just make all the shading black if that’s your thing. Shading could be under the lip, on the neck, or a handsome squidward jawline. Personally I ethier shade a LOT or a little on the eyes. You can also highlight things specifically, hair, nose, chin, forehead, under the eyes. If you focus on the face and just slightly on the hair people love it, If you focus on the hair and barley on the face people love it, If you focus on the outfit and NOTHING else people love it. But in the end I think you did a good job and it’s kind of giving stained glass. I don’t know where I went with this but I hope it’s helpful. BYE!
