My guess is the artist went overboard at the beggining and overextended themselves time wise. At the beggining rhey used a lot of 3d posable models, to get interesting angles, paid attention to details, redrew 3d backgrounds and so forth. Now it looks like they stop the proces at the earlier stage and cut time consuming tasks like posing the dolls and they just draw quickly over the sketch. Same with backgrounds, now they are just pixelated screengrabs.
not complaining, just saying...the art is like super inconsistent in these panels - esp the lineart it be hella thick sometimes
