They look alright Gary. Personally if you are using Photoshop I wouldn't use monochrome. Use grayscale instead as this generally looks a bit better and is a less saturated.
Gary, do a search for a program called "GIMP" if money is a factor. Its Freeware and I love it. Almost like Photoshop and it does work. Actually, I have PS at work and I prefer GIMP. All my stuff I do with GIMP.
