I love plants so that’s what I would do there. Not much help LOL. But maybe updating the paint with a lighter color could make it more cheery in there.

Another thought is maybe changing to different planters and/or adding a couple other elements in there, like a lantern. Just be careful of too much which will look cluttery.

Thank you so much!! ♥️

Can you take a pic from further back. I don’t see any seats. I also think that’s a lot of plants. I love plants but maybe do st lower down in the middle of the table. Like an herb garden and add a cushion to that window sill. New shades and remove the sign above he window. Maybe paint it a blue. Or even just white.

Is the wall color as gold as it appears in the photos? I can't tell how much is actual color, how much is lighting, and how much is photography, but the whole room seems very yellow/gold. It looks like there is a covered porch or patio outside that limits the natural light, so I would be looking to increase the amount of artificial light, and probably increase the color temperature of the lamps as well (up to 4000 K).

Does your sister just want a change or is she specifically looking at what's currently "in" and thinking, "I want that"? If the latter, I'd probably be looking at paint color (grays may or may not be going out, but I don't think golds a poised to come back in for a while. Maybe a greige, or white, or blue). Changing the light fixture would also be a relatively easy update. A new window shade could add some color and pattern.

If she's not as concerned about trends, I might focus more on artwork and the arrangement of the plants. I like the plants, but evenly spacing the pots looks a bit uninspired. Decorators like grouping odd numbers of objects (so 3 or 5 rather than 2 or 4). She could change out some of the pots so that they look more cohesive (this would be a way to introduce a new color if she wants).
