WAY too much detail. What works in a normal work of art doesn't always in pixelart, and such a strong glaring pattern of bricks is among the things that doesn't work so good.
Try to tweak the brick pattern to be more impressionistic than literal, meaning reducing some of the details or colors. The off-white is super glary, and I'd reccomend you swap it for a more earthy color that doesn't clash so hard like brown or a darker red.
As a bonus, it'll make the bannisters and awning decor less harsh to look at!
