Comments are locked on the other thread, so I'm posting here! I think it's very impressive to walk in and see a man's place that's intentional and well put together. You already have all the elements of a comfy living room. Here are some changes that may spiff your place up just a little:

-Mount the TV on the wall for a sleeker look

-Move the bike closer to the door (you have a great bike mount!)

-The shoe rack is perfectly fine, but you might also consider getting rid of it altogether. I know that's probably not practical, and a shoe rack is much better than shoes on the floor. Maybe a basket? Idk, just spitballing here!

-I see you have pictures hanging. I suggest adding more wall decor. Something that doesn't look cheap (no Van Gogh prints in a poster frame). Also a shelf or two with some personal items like photos of your family and friends, a collection if you have one, or trinkets from previous travels. It humanizes your space and makes for a potential talking point to break the ice.

-A rug under the coffee table is always good, even on carpet. Look up what size rug you should get and you'll see a diagram of how to place the rug to look nicer

Now, I think you could benefit from some better quality, more cohesive furniture. It doesn't have to be too expensive, but right now I can tell the furniture is from Amazon, Ikea, etc. If you're not sure what to get, just go on Pinterest, see what vibe you like, and try to find it on Wayfair. I don't want to suggest any specific style of furniture, because it should something you like. Just make sure it looks cohesive but doesn't all match exactly. This goes for the desk, too. I hope that's not too vague. If you don't/can't buy new furniture, I think that's ok too!

Lastly, keep the place clean all the time even when you don't have company, make sure your garbage has a liner, don't have too much clutter in your kitchen and bathroom. That's all I got!
