Hello, I'm looking for feedback on these value studies. I'm looking for how I can make these look more believable, as it feels like I'm just putting down outlines and then colouring them in. I also feel like I dont know how to transition between halftones and shadow. Any type of feedback is appreciated. Thanks!
