Enhancing dark areas

Hi all, I wanted to ask about a little issue I’m having that I’m not sure how to fix exactly. I’m trying to light a bedroom and I’m doing some tests for the lighting now. I have a directional light for the sun and a point light with inverse square without casting shadows to simulate GI. But I can’t get the shadowy areas that are suppose to exist below the bed, desk and drawer. Everything looks very ambient. Can you give me some tips on how to deal with this contrast issue?
