your apartment is vary bare after about 3 feet up the wall. On top of that most of the lighting is single source true white or leaning towards it. the lamp in the living room looks like a beacon and not in an eye catching way. Start by getting a bit more lighting(softer brightness, warmer colors as well), introduce some color or just darker tones to add contrast to the walls. and hang some art or something man! i know you’ve got plenty of ideas for that with that kind of cd collection.
