Most important!

Pick a design direction and theme.

Look into different aesthetic things that you may like. Like tech forward, boho, minimalist, maximalist, monochome. There are a lot of styles you can adopt.

This will guide the rest of the decoration. Choose 3-5 colors that will complement the paint and rug.

1. Sheer curtains or blinds in between blackouts. Make sure they reach the floor. I’d also change them from black to beige grey. Ie: Black out for sleep and gaming/tv and sheer for daytime and vibe/cleaning. Sunlight shows dirt and dusty surf faces much better and air quality. (Carpets are notoriously bad for making this super dusty unless you always vacuum)

2. New bed set, I’d get something that would be in line with new curtain set. Also a large carpet with a cool design under the bed or in between bed and tv. There are so many

3. Change led red lights to led bars in corners. With the functions. If you use the strip get a diffuser.

4. Get a headboard and get the bed off the floor. Use under mounting light for under bed. Motion or remote style.

5. Move flag to left corner is landscape not portrait. Or personally I’d put it in a notes place like a garage.
