Hi hi! Interesting design! I would say most of the picture was correct but proportions were a bit all over the place. Remember: render can't hide errors in construction. That's why we use mannequins to correct ourselves as we draw human figures. With that we check perspective and proportions and by introducing references of human anatomy, we can translate simple shapes in complex organic ones. Once we fix our anatomical errors,we move to shadow placement. Setting up a light source—in this case, the light from the very top—is necessary for a decent render. Place the shadows on multiple levels, align the character components with the main shadow, and use a neutral color for the shadows (typically warm for cool light and cold for warm light). You can experiment with textures on the drawing's light side during the finishing touches. Over flat hues that should not be overly bright or dark, both must be balanced (not too dark or too saturated). Make sure you pay attention to how you place shadows on the body by utilizing references. Treat them as simplified geometric forms first and then break and form shadows to follow the form.
