So many great choices! I ended up choosing the view looking towards the back as I had already unpacked a lot of my art supplies on a table in the window in the front (if I finished quickly, I could sketch my view outside the window). Also, this view captures the great kaleidoscope-like artwork on the wall and ceiling.
I practiced using Steven Reddy's techniques from his Craftsy class, Sketching Interiors: Structure, Detail & Play. First, you need to consider several vantage points from which to sketch, then, make a thumbnail compositional sketch - identifying the foreground, middle ground, and background. Next, you block in the major shapes of your sketch in pencil and then, do a contour drawing of all the tangible edges in your sketch. After that, you apply a series of ink washes (1) a 25% India ink solution over all areas that are not white in your sketch, (2) a second application of the 25% solution over areas that you wish to darken from your first pass, (3) a final application of a 75% India ink solution on the darkest areas of your sketch.
Here is my sketch after following all of the above steps:
