I'm not really that big on hdr and I've no idea what a "natural" one is. This doesn't look overly processed to me so that's a step in the right direction. I can't tell if it's the girlfriend's laptop screen or my eyes but the mail box looks a little stuck on.
The main problem with this for me is the subject matter. It's a suburban street, there's nothing here to hold the viewer's interest unless you have a particular penchant for cul-de-sacs of the world. Just my opinion.
