Nice stuff, i really like your pose studies, very nice and very fluid, believable and dynamic. For the most part your anatomy seems good, but there are a few issues on some of the pieces, so double check or use a reference. The major thing I see on the larger drawings is that your anatomy is falling off the center line, for example, the abdomen is falling off the center line of the chest and the neck. It's happening in a few of the pieces, not all of them. You got some nice designs as well. Keep up the good work.
