I can't exactly help with much since i'm an student too, but i'll point some small stuff i noticed. 1. the neck doesn't curve that much even with the head looking down, and it must follow the spine curve. 2. the trapezius muscle helps shape the neck 3. the esternocleidomastoid attaches both to the clavicle and the sternum m it doesn't curve musch aswell. for the colors i think you should put the whole piece in grayscale and compare the tones, the characters colors and the background color is almost the same, try making the characters shadows darker and making the background slightly lighter. | Artwod Feedback
