My studio is also in the basement, but I do all my fabric things there - quilting, sewing, and embroidery. It is my "she cave", a huge 14x25. I had my concrete floors stained a warm brown color, and I love the look and easy care. Disadvantage is you have to leave the house one night while it is being done, but it is a permanent solution. I do not have a long arm, so I don't worry about standing a long time. If I did, I would install the anti-fatigue mats that industrial companies use. For lighting, I had a nice chat with the lighting guy the contractor sent over. I wanted lots of light and even light (no shadows). He ended up with large fluorescent lights and a type of bubble coverage to diffuse the light evenly. They are wonderful! I know I lose "natural light", but if I need a critical color match I walk upstairs to the windows. For electrical, I had them put in four outlet sets at about 4' above the floor and about every 4 feet. Lots of options for rearranging things.
