Ariel VS Chrystel FIGHT!

You should study Japanese forms of yari (spear). The way she's holding it makes it look like she's wielding an axe, and it is bad form.
maybe something closer to the Nioh spear stances, which are legitimate spear techniques.

Or, if she's more of the kung fu type, what with her being a graceful elf and all, consider a more kung fu-style stance. Like Shaolin monkey kung fu with the staff. Or maybe even something like Tomoe Gozen or Guan Yu. Both were incredible skilled fighters using the polearm. I'd say she'd be more of a Tomoe Gozen-style fighter, what with her relation to that one asian slave chick.

Just a friendly suggestion to help animate your fight scenes.
