Nice lookin stuff as always.
noise isn't always bad.
Take the top one, but re-do it w 0 saturation, bloom it a bit in post, and let the image be pretty noisy from the render, and you'll have an "artsy B&W" image that will look a lot like a photo from a high school / college student.
Oh, and change the focus to the faucet in the left, rather than focusing it on the wall in the back.
- first pic made noisier with some blooming, curves, and B&W adjustments
