A good thing about Anuki are the very very interesting aspects about aviation. I know little about planes but it was fun to see them in action. Also, the aviation school was kinda cool.
About the art: it wasn't too bad, really. I kinda liked that they threw in American-style art while mixing it with Korean manhwa style. The planes were drawn quite nicely too, though it was a pity you couldn't tell apart the friendly and enemy planes.
A bad thing is that the plot often fails to maintain coherence and constantly shifts from scene to scene, so it can be difficult to figure out the storyline. Though at the beginning, the story felt tighter but then it started to skip more and more. Hence, there aren't enough moments to care for anyone at all because it's all rushing towards fulfilling the overall plotline.
Another note: the plot mainly focuses on fleshing out the main cast and story while the rest of the characters serve as props(though highly visible). Hence, more of the pages are dedicated to the main cast while many different sub-storylines are rushed through and concluded rather swiftly, with various side characters being used and then discarded. Sure enough, you don't ever see some of the characters ever again.
A good thing is that it at least attempts to depict war for what it really is: not one of romanticism where war is simply about glory and fame but one full of loss, blood, fury, sadness and tragedy. A shame there isn't enough of it to really cement in these themes.
Conclusion: It's a real pity that the length of the story didn't do the plot any justice. This series would've done far better with an added 4 to 7(or more) volumes because the writing seriously felt highly disjointed. And the ending seriously sucked. 🙁 I mean... what the hell happened to everyone else? 😕 And what about the main character's feelings and so on?
