Just another noob's opinion but hope you don't mind:
Personally I like the 2nd and 3rd staff, they look more darkness/void to me and are supplied with some more interesting sculptures.
The 1st one looks kind of a spear to me. Though I think it may work with some directional or shooting magics, my first impression is still that of a spear. Maybe more indication of some magical nature may work.
As for the character herself, maybe you can introduce more interesting features to give her a more original look. Right now I'm attracted to the spikes, it gives a contrast with the flowing body. Maybe you can push this point more
I joined DWIII for the learning experience too, hope both of us can do well and finish this thing
