You have a lot of talent and your gallery is very impressive. One thing you may want to work on is your shading as it's a bit flat. Try working more values into your pieces to create a greater sense of depth. Reserve the white of the paper for the whitest of highlights and the darkest black for the deepest shadows, and gradate everything else inbetween. I used to shade like you do too, but I found that studying the bones and muscles underneath the skin allows you to get those shadows placed perfectly, and shading in straight lines/hatching will help to build form.
Like I said, you've got a lot of talent and you're very consistent with the quality of work. But there's always room for even a master artist to improve. smile
