a brick veneer is rather expensive. doubt she wants to sink in that much money. can you paint? (the walls....or art) a new color would breathe some life. you have great light. I'd do a lot of greenery and hanging plants. you don't have to cover every inch. do a nice piece of art behind your desk, and your diplomas and such on the other wall. what you don't want are a lot of little things hanging on the wall. Ikea has some great hacks for long wall spaces. look up some of those on Pinterest.

Here's what I might try: Obtain a L-shaped desk with a right-hand return. Position the return along the window wall to the right of the window. The desk extends away from the window wall towards the closet (when sitting at the desk you look to your right to look out the window). Allow some space between the return and the adjacent walls to eliminate the impression that the furniture is jammed into the corner of the room. Check if the "cable box" can be mounted vertically. If so, attach a piece of painted wood to the window wall and hang the cable box on it. You don't want to set the cable box on the desk. Unless the computer is enormous, obtain a bracket and hang the computer underneath the return. Position the computer so you will not bump with your knees it when sitting at the return or desk, or switching between them. Attach cable guides to the underside of the desk and return to keep wires off the floor. Optionally attach a keyboard tray underneath the return. Obtain a table for the printer and position it under the window to avoid putting the printer on the desk. If the printer must go on the desk, put it in the corner near the window. If there's space, put some shelves along the wall between the window and the closet. If not, hang some shelves or cabinets over the return to the right of the window. Optionally change the closet door to a folding door so it doesn't project so much into the room. If there's space above the safe, attach some shelves or cabinets there. -- amateur

How about you tidy up that drawing, add the window sizes, door opening inches and THE SIZE of the desk you are planning? A picture of the desk? Even better. The help here is free, at least put in some effort.........: ) Number clarity is helpful, a 4 , a 9, etc We're lazy? Okay, we're lazy. But it's free.

Based on the size, I would suggest doing a gallery wall with a collection of art.
