Hey there! Nice job here! I believe it's a solid drawing. I’ll focus mainly on the character’s proportions/anatomy, since they’re currently a bit off. First, the pose is somewhat confusing. It looks like the torso is twisting, but at the same time, it feels like a 3/4 view. Because of that, I chose to interpret it as a 3/4 pose (also because female bodies are my weakness and 3/4 is the easiest angle for me haha). The torso appeared slightly too long, and the head placement made the neck look a bit elongated. But what stood out the most was the size of the hand; it was very large! On top of that, the guitar also felt oversized (the lower body made it look almost like a contrabass). I also did a quick gesture sketch of a version where the torso is clearly twisted while the pelvis stays in a profile view, which might serve as a helpful base for you as well if that pose is the main option. Regarding color theory, I don’t have much to add; it works well as you’re handling it. If you’d like to introduce a bit more harmony into your shadow colors, you could try slightly more saturated blues (leaning toward purples) in areas of ambient occlusion or places not affected by direct or bounced light. And in your lighter shadow areas, you could incorporate more cyan tones. I think that approach could make the piece more visually interesting. Hope this helps!
