Well JA, I got all excited and today we assembled the bed. Very long story short, the bed is assembled but DS still has his cot in his room and is sleeping in that tonight. lol
I played around with the bed layout, there are really only 3 positions for it to go. Sketches below:
The 1st sketch looks the best as the window on the top wall is a high window and the bed is centred under it, this layout definately looks the most balanced in the room BUT this means is there hardly any floor space either side of the bed for DS to play.

And I don't think a feature wall would look any good on the wall with the high window.
The 2nd sketch was what I had in mind originally with my striped feature wall along the one wall that doesn't have windows or doors through it. But I don't like entering the room to see the side of the dresser there (which you also see from the kitchen looking down the hallway). Pro of this is that there is alot more floor space having the bed pushed up against the corner of the room.
The 3rd sketch also has good floor space, but I don't like the bed facing the door
What would you do??
PS, the door to the right is the main door to the room. The door on the left is a wardrobe door. The dresser does not fit along the wall inbetween the 2 doors (if it did that would make life so much easier!). The dresser is the smaller blue rectangle (it is fairly large though and full tallboy height). The narrower rectangler is a low bookshelf (hence under the larger window as nothing else will go here)
