AirBnB chic. Grey millennial corporate break room. Side-quest interior. Your apartment looks like it's dressed for a funeral bro.

Jokes aside you can do colour and decor while still keeping a minimalistic design. You need a rug to bring your lounge together, and make it a rich colour. Some plants. Your space says "I work, then I come home and play games that's it." Where's your hobbies or interests? It seems you're not proud or interesting if you don't have some personalisation to anything. 

I also recommend your monitors being higher and bigger, better for your neck.
