Make => coherence... with time, I realize I can really like any style or story, as long as it is coherent and feel sincere/honest. This is hard to define any how-to, but you just know it when you read it.
Example 1 => Resentful Scars from Chloe Beny: drawing, pacing, emotions, all are aligned... it's gentle, intimate, slow burnt... very nuanced and aesthetic. The message and medium are both grainy, sanding layers off, somehow mechanic and thus very coherent. You wouldn't expect flashy colors, massive text bubbles, and 'splash'; unlike:
Example 2 => La Mujer Blackamber from Jimi Macias: Paneling, coloring, character designs & movements... it's catchy, entertaining, fun. The story doesn't let you rest and ponder too much, you just hop on and go for the thrilling ride.
To me, both are good because they're coherent. You can almost feel the author in both case (or at least they're good enough to make you believe that you can): Chloe's delicate emotions in example one / Jimi's fun and will to entertain in example two. Now if you mix art and story from both examples, the result would probably be pretty and efficient, but I wouldn't like... it'd feel forced, and I'd feel cheated...
Coherence can go a long way for me. If a work is true and sincere to its message, it generally shows. And when it shows, I'll want to join because I'll be curious about what the artist is doing. I'd feel that the work is real and worth being read. Coherence can easily make me overlook blatant art or grammar mistakes, and it can make me invest in genre I'd normally not follow...
On the other side, I'll drop perfectly produced stories that ring false very quickly... and obvious markers are generally backgrounds & vocabulary... these can kill coherence very quickly...
