I feel like I'm a bit late with this but what the heck.
Excellent drawing style, in my opinion. You've managed to put a whole lot of character in the few lines you use for the face, which I think takes quite a good understanding of facial expressions. Also, the way you draw, I can tell the sketches are yours just by the style. I like the kran and the klyros most so far, as the kran has an interestingly chiseled appearance that imbues a lot of life in kra and the klyros is a well-drawn depiction female klyros, which I don't think is drawn that often or that well. She gives the appearance of being very lightweight, as if she could soar up into the sky in a moment's notice. Graceful is another fitting word. Maybe another aspect of you style is depicting movement well in your art, just as you can depict expression.
Itching for more.
