Writing: dialogue is good, but it could be more concise:
"you even managed to absorb some of the heat, didn't you?"
"I'm impressed."
"But this ends now!"
Even and managed are a bit redundant, didn't you is also a bit unnecessary in this sentence. It could be written better while keeping the same tone and style.
"I'm impressed."
"You managed to absorb some of the heat."
"But this ends now!"
"Ice magic too, and she has three elements?"
"Who is this chick!"
again, this is a battle, so you don't need to follow all the grammar rules to fit the situation. However, "too" should be added in the end to put more emphasis onto the ice magic. Otherwise, it loses focus to the three elements in the sentence, which I am guessing the reader already knows about.
"Three elements, and Ice magic too?"
"Who is this chick!?"
Another quick one from another chapter:
"Not gonna use your blade?" -----> "Gonna use your blade? " (Sounds more like a taunt, which seems to fit the panel)
"Won't need to" ______> "No need." (Situation, since they're in the middle of fighting, then it's most likely that they're getting exhausted, so try to make the battle dialogue more concise, so they speak everything you're trying to say in 1-3 sentences." Or split it up between descriptions.
"Ballsy, OK!" (All good, love it.)
For a quick review on the art:
Not really a artist guy, but I saw one panel that got me lost, so maybe move the character up a bit so the flow doesn't break.
