I don't know if your photographs are b/w or colour, which can make a difference in how you treat them, but I would suggest that you pay a lot of attention to how you frame them. Depending on how many they are, and how you place them, you may want to frame them all in the same way or in styles that coordinate well.

Your room looks beautiful. You might want to consult a local expert in framing to do the best possible job.

(Some good advice on this web page.)

Can't really see because we can't see the walls. But I do love your sectional.
