This small space may give off a feeling of claustrophobia. This is a small room but with a lot of things going on. I personally enjoy this look because I believe there is enough balance and looks like the perfect place to drink some tea.
i like the tin roof, the seating and of course the fireplace....but could be like this outside at grill area without fireplace. nice overhang (like you already have) and an open area.... Just like the look overall. kind of calm and peaceful.
