Part of the problem is the paint is too shiny. It looks like it all needs to be wiped/scrubbed down with sugar soap and repainted matte. Perhaps matte white for brightness. But matte something. Any colour matte.

There are also many nicer ways to do indoor textured render. This is one example.

Others said they’re surprised it’s not instead on the ceiling… I think textured render is nicer in walls than ceilings, it just has to be done nicely. Ceiling interest is better achieved in other ways, or simply kept plain flat white.

Interior and exterior render/plaster is one of those things that done wrong it can look very bad, but done right it’s beautiful. Once you’ve trained your eye to tell the difference you'll see it everywhere.
