this is really good!!
just a tip, try to make solid lines instead of it just being sketchy.
and use shades dark purple (because u chose purple for eyes) to color her armor and cape, itll look much better than just black and grey. and the highlighting can be done with light blue.
this will make the colors pop
but over all, i love her! and the compsition, the anatomy and her character is just great!!!
