I think you could push the posing more. The impacts don't really feel like impacts to me. They sort of look like they are "going through" the motions, and there isn't a sense of weight or speed. This is also due in part to the far away camera. Don't be afraid to crop in close and focus on the impacts themselves.
The panel where she is running, have her angled forward more, and push out her back leg, it will make her seem like she is lunging instead of sort of jogging. The dude in the back could be squatting a bit more to show the build up of energy.
For the next panel you can exaggerate the sword and her weapon, make them a bit larger perhaps. I assume she is blocking him but the action doesn't really seem that way, it is more that she was trying to hit him and he made an easy block. If she was going to hit him and he blocked the motion lines don't indicate where she was trying to hit him.
For the next panel, you can indicate more energy by drawing the spear bowed and having the guy rotated more at the waist, and cropping the panel in closer.
The next one might be better broken into two panels, a close up of the sword hitting the spear, then her winding up to hit.
The next panel might be better from another angle, to show just how close/far she was from hitting him. The way it is staged right now it doesn't look like she was very close at all.
Overall, watch some fight scenes and view some other comics and see at what moment they choose to focus on, usually right at the hits, not the windups. Exaggerate things, the bends, the poses, the sizes to help with danger, and push the poses more so they look a bit more dynamic.
