Please show other pics of room as well as a floor plan and measurements. Thank you. Do you have an inspiration item such as fabric, wall decor, or loved accessory? How many people usually use this space (not inculding guests)? Please put ceiling lights on a dimmer. Good lighting for this room (to start with) is a table lamp or wall sconce in each corner at chest height. Are you going to keep the rug? Please have a plan and budget before you do or get anything else. Measure twice, buy once!

Single cornered rod. Have the curtains stack to the far right and left with one stationary panel in the corner.

Room does not look high enough. I would go from ceiling (top molding) to floor with simple panels.
