If you'd like to receive suggestions/advice, you will need to add more photos of the room. We can't really tell much about your style (or the room itself) based upon the one photo.

Trust me - if you add more information = additional photos + if you have any special needs that you'd like to address by what you add to this wall (for example, based upon your one photo, you are probably going to need storage for baby/toddler items/toys - unless you have a solution to address that need somewhere else in the room), you will receive quite a bit of advice/suggestions.
