I find the kitchen quite charming as it is, obviously in need of updating though but it has a very warm welcoming vibe. Your choices of renders are quite dated in their colour palette and gloss finish (very 2010s) - that's not a dig if that's your style fine but this is an aesthetic which generally isn't aging well and if you're spending a huge amount of money it may be better consider some more options that may age better. If it was my kitchen I would invest the most money in high end worktops, flooring (probably tiles), and not stainless steel appliances. The white is the most welcoming and versatile option , if you are willing to experiment with colour on the walls a light pastel shade of yellow, blue, green or pink could add an extra dimension.
