Hi, I've started working on my B-W Challenge last minute and would love some feedback and critiques. I want her to be some sort of death angel from a futurist world where people would worship her. I can't decide what feature to focus more to fit the 70/30 design proportion. Also I never know when should I add more details (in her legs for example) and when I shouldn't. Please fell free to give any critique, thanks!

Hey everyone! Nice to meet you all! I've just got here, I've been looking to improve my character design skills and digital rendering too! I'll leave a drawing I did for uni :) Also, is there anyone from Brazil too?
