If it's a good picture in B&W, then it's a good picture.
I've gotten into the habit of displaying and reviewing most of my images in monochrome. Most cameras have this function. You still shoot RAW but you display in B&W. This is particularly useful to analyze light. By removing the color aspect of the image, you simplify it down to luminosity.
This allows me to focus on the lighting and see images more clearly for what they are. Try it :)
