Oi.
I'm not basing this on nothing buddyboy.
Look, how often does Bleach have backgrounds? 0.1% of the time, nowadays.
however within that 0.1% of backgrounds Bleach does have, Kubo has drawn trees, rocks, desert-ish areas, buildings of various sizes and types.
He's used vanishing lines, geometric and organic structures.
all of this is present in Bleach! All of it.
Just in the same way he has drawn a lot of unique people. Some incredibly gorgeous, others very manly or weird. You could argue most of his female characters look the same, but hey, he's a manga artist, they do that.
There's two or three things you could argue:
1.Kubo is slow at drawing backgrounds or finds them difficult, so avoids them
2. Kubo's desire to be inventive in terms of designs and scenery are extremely shallow, so he tends to just draw the same stuff most of the time
3.Kubo can draw different people, but clearly prefers taking the easy route and making most important characters very similar in terms of design either for personal preference, or cause he finds "weird" designs hard to do.
But you cannot, and I repeat, cannot say, Kubo is incapable of producing good quality backgrounds in terms of artistic talent.
Here's why: Consistently, when Kubo does draw something he barely draws, say, a tree, he succeeds at it.
He clearly shows us, the reader, that he's fully capable of drawing stuff he tends to avoid. This means that he's proven several skills through the course of his manga that he barely applies.
The easier solution as to why is clear: it's not that he can't. It's that he won't.
Just going back to chapter 10 or 11 of Bleach should remind you of the time Kubo did draw backgrounds and stuff. I think he's an idiot for no longer doing it, but I don't understand how you're capable of saying "he can't".
note: I'm seperating sheer artistic capability and originality into two different boxes here btw. You heavily focus on Kubo's artistic merrits, not his originality, so that's what I decided to focus on.
Yeah, he definitely has the capability, but chooses not to. What bothers me are the people who call it an "artistic decision" rather than just laziness. There's nothing artistic about deciding that everyone can fly so you don't have to draw the ground anymore.
