I'd love to help but I have to admit I have almost no idea what is going on in your drawings. Clearly there is some intended exercise but it is really hard to distinguish what are actual forms and what are cast shadows. It looks like one of those "impossible object" illusions. Can you show us what the objects are (by silhouette perhaps), where the light is coming from, the intended ground plane, and perspective grid maybe?
