How can I make my kitchen look nicer or more comfortable?

I am renting first of all so major changes are not okay to do. I moved into this apt and to be honest it’s a pretty blah apartment and I am trying to do what I can to it to make it nicer. Every other room I am content with(or atleast as much as I can be) except for the kitchen. It feels open and cold. Not to mention the UGLY 1970s stove that is stuck in there and the fridge(spacious but ugly) that doesn’t help make it much nicer. I was wondering if you guys had any suggestions on how I can spruce it up a little, make it feel warmer or more comfortable. Originally I had red curtains up which you will see in the photo but it made it kind of depressing so I decided to play off the ugly color of the stove and throw in some yellows. There is a curtain on the second window that is yellow that I was just kind of testing out to see what I thought. What do you guys think, what should I do?
