Second floor outlines

The one thing that was most assuredly missing(which is why I managed to snag this house so cheap) were the interior walls. While I'm thinking classic color scheme on the exterior, I've already been contemplating possibly sticking with the open concept and really going more modern. Though in the same breath, I've come across a lot of the more classic(think English Rose) wallpaper patterns that I could see working really well in decorating with more rooms, so I may just end up cutting a few new walls and seeing where the house directs me to go with decorating.
