Cute schoolgirl trapped in a bubble (3 versions) (Pixiv Fanbox)

An illustration set I made for a commissioned story. I'll post it on Pixiv along with the story in a few days, but I made the illustrations first so I still have the story to write, and I wanted to share the drawings with you in the meantime! Ah... the bare armpit of an innocent girl in trouble! also this is so obvious but I just added a bit of skin color to the front of the shirt and it gained depth instantly! Also I tried drawing hands again, to practice. I had to re-draw the hand behind her, but eventually got to a point where it looks okay. I still need to improve a lot at that, so that will be my goal next! I'll try to study and practice poses and anatomy and hands to get more comfortable with it.
