I would move the dog crate to a different place. Pull the sectional out from the wall so that you can place 2 end tables by the sofa. Could you purchase a large console for under the TV? It would not only look nice but could also prevent the door from hitting the TV.

You did not mention any other concerns, but if you are planning to make other changes, I would get lamps for the new end tables, add curtain panels to the window, add a large colorful rug and art on the walls.

Thank you for your ideas! Trying to implement some of these! Hard to work in a small apartment 🤣

Bought these ottomans!

I would agree with the previous comment, finding a counsel table for under the tv with open space underneath to store ottomans or even a built in or floating media center. ( I used something similar in my 80’s living room update). An area rug will help make the room feel more inviting, cozy, and curated. It also looks like you tv is mounted much too high for ergonomic tv watching. The center of the TV should land somewhere around 61 to 65 inches from the floor. I would also agree with removing the dog crate and pulling the couch away from the wall a bit and getting end tables or purchasing a dog crate end table (I believe some are even sold on Houzz). Next you should layer in lighting with either a floor lamp, wall sconces, or table lamps. And to make the space feel a little more lively you can add a faux plant or two and include a large piece of artwork over the couch (nothing too dark or visually heavy though)
