There are so many really good art pieces here! I'd offer critique for people asking, but I have no idea what you're looking or if I could even help :/ which is sad because I am always looking for critiques on my work and I'm sad when no one can offer me anything. I did find the best critiquing I ever got was from a scientist, though.
I do pencil/ink drawings as well as photoshop.

A man I had a dream about. He was standing at the mouth of a cave, I was behind him, and he looked over his shoulder at me, giving me a sad, knowing look as if the weight of the world was on him. I wish I was better at capturing expression rather than this soulless creature... Done in pencil and ink and retouched in photoshop:
I love tiny detail work. We had to do a 3 part project in a class, a stippling version, black and white version, and a color version. I had finished my original project far too quickly for my taste so I challenged myself to do this one.
If anyone is interesting, here're my favorites on a photoshop contest. Not pictured here just because I know some people aren't comfortable with seeing a woman breastfeeding. I photoshopped her into scenes like the Mona Lisa, or Venus de Milo, even the Sistine Chapel ceiling. There really isn't anything to see, the baby's head covers pretty much everything in that aspect.

You've got an amazing knack for the value scale! Very well done on all of these!
The thing I'd point out is rather minor - the lines in your subject's hair can be a little harsh sometimes, they'd look a lot better if they were softened.
Other than that, I don't really have anything. Beautiful job!
