I love your studio. It is great to have a space to work without interruptions. I ended up converting space over my garage. It came out great and I love having the separate space where I "work".
I think the best thing I did was to make my own desks. I got 2 Ergotron bases that are stand/sit desks. I used solid core doors (cut off) for the tops. One is a flat top desk and the other I built a tilting mechanism on so it is like a drafting table. It is nice to have skylights over them as well... but that is just a bonus.
My computer is on an Ergotron lifting mechanism as well. It is nice to be able to stand and sit at will.
Here are some pics...
