Good job Chris. You might want to try moving the camera around. Imagine looking down on a person or looking up at them. Many of your drawings are of a person standing. Try drawing someone walking up or down stairs. Or looking down at them on the sidewalk from a building or looking up at them from below, like in a sewer drain, like PennyWise.
Get familiar with being able to draw what you see from the viewpoint of other people or from places other than where you are seeing from.
