Oh wow, I actually read your comic on webtoons (and subscribed there) xP Ok, here is my review!!
-Art-
I love the use of color and gives a clear feeling of the season (spring). I like that in the first few panels you establish her room, the town and school wish I am sure will be center pieces overall to the story. The outline is perfect by not going fully black outline but using the color of the clothing (though a darker shade of course). It really works with romance type stories!
The amount of backgrounds you have is amazing, I think I rarely see any panel without background which is great, gives a lot of life to the world they are in.
Great shadows too, I do believe softer shadow like the one you are using do fit love stories more compare to hard shadows use. Great lighting too, love that it changes depending on the scene and location giving a good impression that she is moving around (and everything around her for that matter).
-Writing-
Is actually what had me hook to start, her self monologue explaining her views of the world and what she loves, the variety of fonts depending on the mood she is (as well as using the text box colo for mood too). Dialogue is easy to follow and understand, great use of font.
Love the effects too, using different fonts there too depending on the 'sound' is great.
-Paneling-
I love that you make great use of the webcomic format as your comic clearly is a vertical style one. I do feel some panels lack border in parts (they have borders in some areas, but lack one to the right or left most of the time. I think closing them completely would make them look better, of course some don't need them (the long ones for example).
Overall great use of webcomic format and love the long scrolling panel,
-Story-
Great intro as it gives most of the details we need to be able to follow the rest of the story. Also great use of the art telling us part of the story without the need for text such as lack of friends, people in her online group losing interest in the manga she still clearly loves. I can feel her loneliness and she just wanting to have a friend to talk to.
I haven't read the comic this is based on, but I do hope things don't necessary happen the same as in that one. I do love the inspiration and it making most of her life about it, but I do hope future events in her actual life story are different from the mange she loves. I think it would be interesting seeing the events she dreams about (the manga) actually be different in real life (maybe similar start, but different when they end).
Hope this helps, you have a really good hook in the start, great art and great writing
