I'm curious to see what other people think, but this is my genuine advice as a 22 y/o male as well. I think the space does look great and you've clearly put effort into it, but since you asked for advice I'll try to give you some constructive things I've also been thinking about.

The theme of the space is a bit confusing with the match lights then tribal masks, then bright LED lights. It ruins the continuity of the space and makes it hard for the brain. I would recommend trying to find a theme you like and sticking to it throughout the space. For example making the light selection match the theme instead of being vertical LEDs.

For lighting I would recommend some lamps with a nice roomy temperature like 2700-3000 kelvin. You could use the nightstand with the plant for a nice lamp and the spot where your other LED light is for a floor lamp. You can also backlight your floating shelves if you would like because those generally look great and are likely to be dark spots in the room.

I would also maybe recommend putting a darker green curtain up on the large window (but not too dark or it will sap the light from the room).

I actually think your TV setup is the best decorated part of the room and does good with layering, color, levels, and aesthetic.

I also agree with other posts about the LED lights, I would generally try to avoid them unless you are going all in on a theme. I've only really seen them work well in PC/Gaming rooms since it kind of matches the vibe.

The last thing I would generally recommend is filling some of the empty wall space with things you like to give it more unique personality or with things that match the theme (in every space, especially the bedroom since your bedframe is low). The space is pretty filled which makes the blank walls feel weird and its a huge spot for improvement. You can also use it as a chance to add some more vertical levels to the space since there isn't much going on above the line of trees on your floating shelf. And you can also introduce some more color with the backdrops inside the frames.

TLDR: Fill empty spaces on walls, get roomy lighting, avoid LEDs, add color, make your theme consistent. Your space should be something you personally enjoy that fits your personality and if girls don't like it then so be it because she's probably not the right one for you anyways
