While I was in the hospital infusion room with my wife, I noticed how well those 1x1 chromed egg crates were able to keep all the light shining down and not to the sides. I'm thinking I'll pick up some panels and experiment with T5s and LEDs to see if that could be a nice compact elegant solution. I dislike those huge aquarium canopies or anything resembling them over my tanks.
Those stainless steel salad bowls can be painted any color to help blend in better. Your shades look fine. Most people here expect a more standard aquarium look to the lighting fixtures and yours look different from anything we usually see posted on the forums. As long as they look good in the room and do the job, it's all good.
