not sure if just my eyes/screen but looks to me like the left image has its top layer more influenced more by the background color while the right image is more distinctly white?
feels sorta like I prefer having a background gap between the coffee and the top of the cup reflecting the background color and so prefer left. Like the cup isn’t 100% full
Yeah, I noticed that too, especially when they are put side-by-side like that.
I agree that the top of the foam on the coffee should perhaps be a distinct colour from the background.
