Word choice is so important. A few changes make a world of difference.
The setting sun reflected off the smooth surface, making the water look pink.
"making . . . look" just doesn't have any ambiance connected with it.
The setting sun reflected off the smooth surface, tingeing the water an unreasonable pink.
By changing making to tingeing, I also got rid of the look. It also reminded me that Bealomondore is an artist. He thinks more poetically than another might.
I played with an adjective for pink. Unbelievable? Salmon? Impossible? Sunset? Brilliant? I finally settled on unreasonable, but I wouldn't doubt that my crit partners may make me change it.
PS This comment is being inserted after the original post. The crit partners approved of unreasonable pink.
