Hey Ryan. I like the composition on the environment piece. You just have to have more lighting on it. follow the basic foundation. Darker foreground to lighter middle and background. then put a spot light on the center of the square or something. For the characters, at this stage of character studies, you want to show lot of variations. I dont think design is strong enough to take it to full render. Do more variations untill you have the version that you feel so strong about to take it to rendering. I'll expect to see your sketches soon.
