I'll disagree about the same face issue. This artist is impeccable at drawing easily distinguishable characters when necessary. For example, compare the Prince's face and build against the MC. They have a distinct enough silhouette, with the MC being slim, while the Prince built like a brick. You can get panels and put them side by side and immediately recognise which one is which.
That was what I were saying about how he at least made sure to distinguish mc (by making him the only one with black hair etc).
But prince compared to
any other characters (aside from really old ones, or ones with a different gender)? Near impossible to recognize who is who (though luckily the prince has contextual clues such as sitting down at the desk).
The usage of various cut ins for Exposition are there for a purpose too. You can notice just how heavy handed the dialogue and expositon of the world are just from these last few chapters that are STILL under the "preparation" arc.
Yes, I know they are on purpose. They just don't actually
add anything. You could follow just as well just reading the text-bubbles and not look at any art, for many of those panels (they do not provide source of the speech-bubbles (rather, they remove it), and neither do they show actual actions. They are used more as if to show who (or what faction) the speaker is talking about at that moment - except the characters are identical, and for some factions it was already obvious (specifically the demons)).
The ones showing troop movements are marginally useful though.
What are the mangaka supposed to do here when the characters are discussing about their thoughts and ideas in a single room with little to meaningful back and forth? They've done their best and used all the establishing angles they could do to ensure that this didn't turn into a Hunter x Hunter text dump page.
They could have shown all characters speaking, and the bubbles clearly pointing at their origin. To ensure there is no ambiguity at any and all times. But yes, besides that there is not much a mangaka has to draw, and it is why those scenes lend themselves well to few-but-large panels.
If there's any issue this manga has, it wouldn't be the artwork. Because the artwork here is technically competent, pretty, and delivers emotions extremely well through the usage of some insane value and shading work. Check out that one panel where the MC had some lights between the pillars hit his face and you can somehow FEEL that it's the sun hitting his face. Now that's some technical prowess.
That is what I meant with how it is good in a vacuum. It is actually gorgeously drawn with tons of details. It is merely that that is
not desireable in a comic. You want simple art that conveys things at a glance, with nearly caricatures as character-design to ensure they are easily recognizeable and memorable (or at the very least, color-coding (though grayscale) + haircut-coding + unique accessories).
ps: though for emotions, I disagree. Yes they are somewhat visible, but they are far from as visible as the emoting mangakas can get away with through a more normal - or even chibi'fied - artstyle. Unless you only meant "emotion of a scene" (as opposed to the character's emotions), because yeah, it can do that quite well.
pps: never felt like some light was specifically from a sun, though. Maybe would if I took some time to look at the panel you talk about in detail - but if so, then that is contrary to the goal and absolutely not how one reads a manga
Like I said in my original comment: the art is great in a vacuum (using your words, it has quite some technical prowess) with tons of details and unusually realistic faces, but that is pretty much the exact issue here.
The issue here is pacing. The manga INSISTS on delivering all of the information that the light novel have in this arc, which in reality, is actually a single goddamn chapter in the novel. This is still the first volume of the LN.
Also I recommend checking out the LN's artwork. It's clearer, but it lacks the polish that the manga has. And it has character design issues that are a lot more egregious. With every single character having one body type and one head shape.
TL;DR
Art is good, pacing is bad.
Yeah I never mentioned the pacing, but I do agree with you that it is a bit slow atm. Too wordy for stuff it feels like they could get away with explaining in some shorter scene. In large part due to how mc has to move between locations all the time and essentially shows us both "mc thinks of something", "mc talks about it with others", "it is escalated [or he escalates it] and mc gets to talk about it with higher-ups", and so on. Not to mention how it tries to convey the interpersonal dynamics in the dialogues through back-and-forths.
It [that kind of storytelling] has its uses, but it is currently taken so far it
does feel a bit like a chore atm, I agree.
