This. Light from below is unnatural. Also, I think this generally would confuse users. I visit at 10AM it looks one way, I visit at 3PM it looks another, and I have no idea why as a user. Even if you paired it with other elements, you've still got the shadow all over the place. I remember about 10 years ago watching a guy in school build a site that had a header that would have full sunrise-sunset based on your time in cute artwork. If you gave your location, it would display current weather too. So OP, I think this has limited use; but its good to explore and experiment and see what you end up with. Perhaps with more thought/iterations you'll end up with something really amazing.
