It has been a while since I draw these two. I am also thinking of drawing a V2 of these characters introduction in one post later.
Glaciss is on the left, Mashiro is on the right.
I got some inspiration for some lighting and shading to try out and I am quite happy with the result for the face, stomach and thighs
Well later on I'll figure something out to do for the back of the hair
Their shoulders might've been a bit broad in this one tho.

Glaciss on page 2 is with her front hair bang without parting/splitting. On page 1 her front hair bang is split a bit to show some of her forehead, which I think is needed to give her a more friendly look. She looks stricter on page 2.

Mashiro with her hair down has a slightly spiky feature to it. Tho her usual look is the folded ponytail with a pink ribbon. She's also about the height of Glaciss now (though about 1-2cm shorter than her) when previously I'd drawn her shorter than Glaciss.
