@kohkeeree thank you for your opinion on the designs, much appreciated!!
Here is some stuff I have been working on for the past few days.
I'm trying to get better at the layouts for my character concepts so there is enough information on my thought process but also so that it isn't so overwhelming to look at.
Her character, is very simple and I wanted to try and convey that. Her style is still interesting yet isn't confusing with the amount of extra accessories. Even the way in which she stores her katana is within her waistband instead of an extra belt.
I am quite happy with the final design for her uniform, it incoporates the colours and also the sort of girliness. I like female characters such as mitsuri from demon slayer who is so girly but incredibly strong, so that's where i took inspo from. Very excited to move onto her and her brothers designs for their "home attire" when not in assassin school.

As I have started a fundamentals of character design course, we are looking at the way the body moves and skeletal structures. it was quite hard to do the distorted skeletal masses as i don't usually play around too much with pushing anatomy but i want to get better at that and create characters that are semi realistic with stylised body proportions e.g, miles morales body type.
