yo, Kyousuke.
Nice pictures. All I have to say is to watch your balance. The second picture is really good. The first one is a little off though.
If you draw a line through ur character (through their center of gravity) you can see that her hips are pushed off to the right. Since her legs are going straight down, her balance is off.
To fix this:
push the hips back over to the center
or
move the upper body over the hips
or
open the legs more so she has a wider stance
keep it up yo
peace
