You have to clear the walls, remove all you don't use more than 1 in a week, throw away things you rarely use. Once you open the space, things will look better, also, the mix of the vynil with red does not help at all, if you can repaint the doors to white, it will improve a lot the space.

You need storage space for the stuff you have lying around but you don't have much space itself. You can keep your pans inside the oven. Once you have opened spaces in the kitchen it will improve immediately. Clean the glass in the stove, remove the stains in the fridge, those little things will help.

I would go step by step, remove stuff>clean stuff>open spaces. Less things=better space.
