Some good stuff, though I might recommend a single thread of all your work so that 1. You only have one thread to maintain, and can easily reference everything(and watch your improvement over time) and 2. your multiple threads don't clog out the other threads on the forum by guys who want commentary and criticism on their work just as much as you do.
As I've mentioned before, I think you should really consider working on your anatomy and 'foundations' before you push into the fantasy realms. I know it isn't as fun, but perhaps a back and forth spending equal time on the hard stuff as well as the fun stuff could work for you. It is an interesting design like all of the stuff you've been posting lately, but it suffers from your lack of anatomical knowledge or foundational skills.
Good luck, and please consider what I said earlier about a single thread for this multitude of pencil sketches.
