General comment - the transition from kitchen to living area is not clear, I think I am seeing the microwave in the LR and something swathed in fabric in the kitchen.
The laptop and little desk - if you were to hook your laptop up to your TV (HDMI cable), and use a wireless mouse and keyboard so you can sit where you normally sit for the TV, you would have a better monitor and one less "thing" taking up space.
I agree with others, you have a lot of visual clutter (especially in the bathroom), which makes your living area seem smaller. I know, I am equally guilty. As others have suggested, little tweaks in storage practices would make a huge difference in the "feel" of your place.
Is that your microwave on the second shelf of the shelves? If yes, it seems low. For comfortable and safe use, I would move it to the top of your little butcher block table that is beside the shelf - what is the fabric-covered boxy thing on there now? If you don't use it, why keep it? For the record, I love my microwave and use it all the time, but I don't have a toaster, a kettle or a toaster oven. Others could not live without them. So it is a very individual thing. Also, there is a clock on the stove, so why have that big round clock on a place where it looks like it could be knocked off. Again, the clock is visual clutter, and not needed.
Does your apartment have a storage locker someplace? If it is reasonably convenient, is there anything in the apartment that you don't use that often that could go into storage (at the front, so you can get it easily)?
When my sister gutted her kitchen, everything went into another room. When the kitchen was finished, she did not bring anything back in until she needed it. After a few weeks, there were still kitchen things in the other room - she obviously rarely used them, so sorted, some went into storage (things like Christmas baking) and some went out. Can you do something like this? You know, turn hangers backwards and see if the clothes get worn, put things some place hard to get and see if you bother to use them.
Your cat loves you - it obviously follows you around, to have ended up in so many pictures. But its litter box is taking up your only free floor space in the bathroom - is it tidy re litter? Could you put that someplace else (like where the laptop is now, but disguised), where it would not be as visible but still easy for the cat to get to? Putting it on a larger rubber boot tray would make it easy to keep the floor clean if the litter ends up tracked out a bit. If you moved the laptop but left the desk, you could put the kitty litter box under the desk, and use the desk for a "landing stage" so things coming in or out have a temporary home. Before I set up a landing stage at my front door, everything just went on the floor as I came in.
I think I am going to go and look at my own cluttered living area (ouch, definitely worse than yours) and implement my own ideas.
