Loving the leaping sith's dynamic pose and composition of the elements focusing on the character. That edit with Binks is also appreciated.
Something about the hood on that vampiric sorceress character, as well as the tarry feel of the legs please me. But I can't help but feel that there's something off about the face, albeit definitely an improvement to the reference. Can't really put a finger on it however.
I'll have to take a gander through the rest of your sketchbook. Keep it up.
