LOL! I'm not an artist, either. I think illustrator is the word you're looking for. So that's what that white rectangle is. A house this size would be full of rooms (and therefore walls), so those back windows shouldn't show. Remove those, and let it be dark inside. Actually, with the sun on the front of the house, all you would see inside are the curtains (the human eye can only deal with so much contrast, then all goes dark)... so add some curtains. I know what you're saying about the clouds and sun. Done that myself a few times, and got the same comments. I think what you did is ok, but that's just me. I highly recommend that you try moving the sun around. The shadows aren't that dark... they won't obscure anything. Trust me, it's the one thing you really need to do. Light and shadow are so important to any rendering... artist, illustrator, or "director". Really! Even if you feel you're just not any good with lighting, any variation helps. You'll get the hang of it sooner or later. You might as well start now. :-)
