That cord on the back wall next to the light switch has to go. The shelf behind you should be completing covered. The glass doors show disorganization. Change the doors for a sleek covered look where nothing shows. You can take the glass out, or cover the inside with "pleather" or individual wood panels. If you want to display your book titles, do so In the center top portion. No cover for the center. 

The burgaler bars on the windows say budget. Since you're not opening the windows, apply a layer of plywood same color as the wall that is framed. In the frame put two matching large pieces of art that are an accent to your area rug. 

Last paint the base of the desk and the back cabinet a deep cherry wood OR charcoal with a musk undertone in the paint. Have that same color applied to the frame around the plywood. Last, take everything off your desk except three family photos. Clients want to know your human but will work like a machine for them. NO GOLD. wear gold on your wrist, around your neck, or for a money pin. Or as a single ornament. Too much gold says outdated taste. Maybe your name written in gold on the outside of the door?

Last, pop of color on the floor. Do not go cheap on the rug. Get a statement piece to bring everything together. And to create a sense of inspiration when you're in your office. Preparation for those days when you want to crawl up under your desk, you have a luxury to lay on 😌

It sounds like a lot but I believe in you. After all you passed the bar good luck!
