Dream of Diamonds WIP by Yutaki

This is going to be my next A3 Poster.
From here on I’m going to Line and Color it Traditionally so this is really my last chance to change things!
This is why I’d like to ask you if you see any mistakes, anything that I should correct or can make better!
Please help me out!
I am especially talking about Anatomy, Composition, Details, Balance and General Appeal of the picture.
Your critique would be highly appreciated QwQ
Please refrain from talking about colors and lines since these are things that are not done yet obviously ^.~
