Nice start, here are some suggestions:
-The camera is pointed down, so it’s really weird to see clouds outside the window.
-The window looks like a picture because there is no light coming from it.
-There is usually a part of the counter that is parallel to the wall, like this.
-A bevel would keep edges from looking too sharp.
-Backgrounds seems a bit out of place, and low res too. You could model that area as well or just make it a corner.
-The spout and the upper right corner of the sink intersect perfectly, making a visual tangent. Those should always be avoided because it makes the image look awkward since there is no depth perception. Helpful video here.
Sorry if that was super harsh, but I would like to see this improve. My first attempts at realism were much, much worse
