As for that first one, the proportions are significantly more stylized than in my usual works. The focus was more on getting a good flow in her pose. I'm not sure I quite succeeded at that. I think the shift of weight through the torso and legs is alright, but I can never figure out what to do with the arms.
This second sketch has a bit more of a story to it. With the help of a friend, I've been doing research and compiling references for figuring out Reina's overall physique. Trying to create a visual balance in a character who is both short and narrow, and also has a well-developed muscular structure, is extremely difficult. I'm getting closer to it, though.
And as for the last one, this is essentially just a page from my sketchbook. Again, I was pretty much on autopilot while doing these, so it's just further head and face studies. I sincerely need to improve my ability to draw expressions beyond "neutral." Perhaps I should very carefully watch some of Disney's 2D animated films.
That's all for this week. I'm thinking that next week, I may do a feature on a series of original mecha designs which I began work on late last year.
