My Studio/ Guestroom redesign

I am participating in the Design Challenge at Debra's Common Ground

I have this great room to redecorate and move my office into that I want to also function as a guest room.
The way it looks now is bad.  typical boy. Don't come in my room and do anything mom!
I know it's messy, but this is the reality, now, but not forever.

I want the wall above to look like this sketch.

And this wall where he had the bed right on the floor.

To get a vintage bed post and old nite table... like in this sketch

We want to turn this completely around and give it a
 French look.

I am using stuff that I already have around. Taken from other rooms that have been re designed.
I have sketched out the look I want, for all the above walls:

I am planning to paint this bureaux white or dove grey and marry it with a mirror that used to be in my daughter's room.

Another great piece I will paint white is a night table that has been sitting in the basement. I also plan to pull an old bed frame from the shed to paint up and include in the redesign.
My challenge is to only spend on paint and a new comforter, because I have so many pieces I can use already.
But as you can see from the sketch, I can't figure out what to do with the entrance.
Here it is now. Below

Any suggestions or ideas would be appreciated.
You can go see the entire Design Challenge Feature at Common Ground

Debra and I would love to hear your thoughts on how to make this room a French Inspired Haven!
