I think you have a good start. I like the wood floor and the bit of trim on the otherwise blank wall.
No direct light coming in your window is a good thing. You'll have harsh shadows otherwise. Are you in between the window and the subject? Or is the window to the side of both of you? That will make a difference with how you bounce the light around, so I'll give some general pointers right now...
Do you have a lamp or something to point at the ceiling and light that up? (I'm assuming you have a white ceiling like most houses). When I was a broke college kid, I bought 2 of those clip on work lamps and clipped them to various pieces of furniture to light up my scene. You don't want to point it directly at the person as that will create a bunch of undesirable shadows but up at the ceiling and towards them a bit.
Put your camera on a tripod-that's always a good idea and you can use the tripod as a place to hold a piece of white foamboard to bounce even more light onto your subject.
Pull your subject away from the wall a bit too. Then you can actually light the wall separately from them if you want.
