I cannot believe you churned this out of that sketch so quickly. I am in awe. Had no idea you pulled all-nighters like that. You'd fit right in at art school.

The colors are great. John K.'s wisdom has not been lost on you.

Eirru's frame and build are too masculine in a lot of panels, even for a warrior woman, which is weird because she was practically naked before and you didn't seem to have any trouble with that. In the "too much talk, fighting now" panel her arms are way too thick (is thick the right word here? bah) even though you did give her a nice smooth shoulder, and her jawline is missing. There really needs to be something to define her jawbone there, especially since if you draw it properly it will help to suggest her femininity. She looks really unfinished there and it reminds me of something but for the life of me I can't think of what. =/ Second-to-the-last panel has similar problems; positioning her hair over her back was a mistake because now we can't tell if she's skinny, fat or what. It's like I said about the silhouette thing, except this is a little worse because it's still confusing even when you have all the information. Also, the perspective in that panel isn't very good, but I know you have trouble with that. For some reason I think you could have drawn a kick there better than a punch, and it would have been much easier to identify, too. I LOVE how Faw looks in that panel, though. Having his shirt come up and reveal some skin as he leans back was a good move, it really accentuates what's happening. Maybe it was an obvious thing to do, but I can't think of many times I'm seen anyone draw that, so yeah.

In the faceplant panel Faw's outline looks wiggly; I think you overdid the ear fluff. Showing a bit of his legs there would probably have been good, like instead of showing just his head hitting the floor you had his lower body landing with it. I'm pretty sure he could fall that way if he was spinning at the right speed. People falling head-first onto the ground like that is something you almost never see in real life (maybe on 4chan or something) so it's hard to not make it look awkward, especially with a character whose anatomy is fairly realistic.

All of Faw's expressions are hilarious and awesome. I'm guessing Eirru is supposed to be less expressive and more serious, but I really liked Faw's face in nearly every panel.

Not much else to say. The panel where she's tripping him is really good; their poses suggest movement well and it was the time you were most successful at making Eirru look strong but still totally female.

Aaand the backgrounds are weak but you know that. Time probably had something to do with it. No trees anywhere. Bob Ross would be appalled.

I'm sorry I didn't point all this out during sketchphase, but this stuff just isn't as obvious until the whole thing is done and can no longer be saved. Still a good punch, though.
