hey @hyoi. overall I really like the samurai maid. I only mention that because everything seems to flow naturally (the dress doesn't seem to rigid).
However something that stands out to me is the back leg - it seems to stick out slightly too far when viewed from this perspective. (it could just be my imagination). I don't think you need to change the position, I would suggest maybe adding a few wrinkles to the dress in the upper area of the back leg.
Also regarding the shin guards (if you decide to keep them) - I would straighten the ones on the right (left leg) a bit. they seem a bit too curved in comparison to the other pieces of armor you have.
Sorry, I tend to write a lot. anyways hope this helps and cant wait to see final one.
