Well, she is a character and as such deserves more attention then a mere grunt. I would call it a very good start. The color scheme is great, in fact I don't remember this chick ever done in these colors. What , i think is needed at this point is highlighting of pretty much everything. I would make edges of armor, edges of sword's hilt and "edges" of her hair much brighter. The skin I would make a bit warmer, she looks too grey, She is supposed to be pale, but not dead.
As for the sword. Try diluted magenta ink, or mix of magenta ink and some blue ink. That concoction will make it darker and colored, then I would take mythril silver and rehighlight very edges
