Looks pretty damn good to me. I opened this thread thinking that we would see a cartoonish mess but I love this one other than the fact it needs that person on the right chopping out. I'm pretty new to all this myself but I'm trying to follow the philosophy of using it to make a scene look like one which the eye would see and going no further. I have practiced in my living room on sunny days. A normal shot would either have the view through the window and everything else dark, or detail in the room and a over exposed window. It's a good HDR practice subject.
A lot of people's efforts end up with no shadows or highlights at all and ultimately they stop looking like a photograph. You seem to have kept a nice amount of shadow, brightness and contrast.
