Are those brick walls, is that why the electrical plugs are exposed? Check into sinking them into the walls. Strip and polish the cement floors... maybe acid stain it when you're done. Those walls need a pin straight level 5 plaster finish if you want a gallery or photograher to be interested. I personally would put track lighting in. Maybe put an aluminum F channel around the perimeter of the ceiling for a RBG LED tape light for color during a special event or to pulsate to music. Good luck.

Could be interesting to find a local party planner and have them mock up the room for a few different party/decor ideas for photos - cool space!
