I really did like the original, so here's what I think of the adaptation so far,
I wasn't a fan of the art at first, in comparison to the more indie style of Ha Il-Kwon. To new readers I suggest comparing the first few chapters of this to the first few chapters of My Heart is Beating in Related.
Ha Il-Kwon draws their work as if it was indie, because it was, it's a webtoon. Paneling is different due to this as well as a top to bottom format of a webtoon makes you consider different choices. You'll see panels more overlap each other, or smaller panels sandwiching bigger panels that gives a different effect if it were to be done in a Manga format. For example in the webtoon you see more of a focus on close ups, which works wells since you read from top to bottom. The manga does this too however you don't realize it because it feels like a filler panel in that format.
However, the biggest change is that there is no color off-course in a manga, meaning the melancholic coloring at times and softer shading gets lost in adaptation. The pool and the protagonist room at times of contemplation or melancholy is often tinted blue, which helps with the tone of those scenes. To add to that, the use of flush instead of shading adds to the softness and almost vulnerable feel of the characters which needs different techniques to replicate in manga that Senta isn't trying to do which is fine. This I'm not sure I'm explaining as well so an image

I do prefer the original but, reading through and trying to find the differences, I found Naka Senta comes into their own by chapter 3. There you feel it get out of it's adapting the webtoon rut and start to become it's own style. So I hope it's a good adaptation by the end, and I could see it doing so.
