You mean improve? The art got better if you compare ch 1 to the latest. (⌒▽⌒)
The drawing style is a little different but I think the biggest change is the coloring. I don't know how to describe it but it's like too perfect. The new chapters are pretty but I miss the sunny pastel coloring.
oh... well, then we have different opinions ┗( T﹏T )┛
i didnt really notice the coloring much, but the art style yes. nothing much changed with fl but ml looks like hes aged a lot(a lil exagerrated) after s1. they all seem slightly thinner, necks are longer and just overall feel anatomically worse than before. yes, i know its "anime style" anatomy, but it feels like they got ill after season 1 and they never recovered their healthiness.
its been a while, and the first thing i notice is the art, did it deteriorate??
