@twinblades Is interesting, is impossible to determine if something is mainstream or not, but I think your story can find a good audience 
Here is the review for Doraji.
-Art-
I notice a similarity in art, but is still different in aspects. I think thicker lines might help giving most of the comic is black and white the line art become really important, when color is use the line are perfect as the color compliment it, but when is just black and white (and grey) the lines look more slim, so thicker lines would help it out in my opinion. I'll say that the prologue is really great hook, the panel looking like shatter glass is a really great effect!
One thing I notice is in that some panels the top of the head looks flat, not sure is cause is story situation (since it keeps mentioning her hair color), but it looks a bit weird when in other is the normal arc way. That is the only thing that stroke me as odd. The art is really good, great backgrounds and the color panels are really good.
Also great idea to use color when a new character is introduce, gives them a good level of importance.
-Writing-
Again the prologue has a nice feel to it, feel like a poem almost. I believe the font use is great and you have some really funny moments (the antique shop 'owner' (we all know the is the wife really :P) complaing about his wife was perfect!). I believe you using the write amount and setup mystery with it (the hair for one).
-Paneling-
This is a great example of using the vertical format of webtoon to great effect. You have great inbetween panels too for slight transitions or for actions the character is doing which are really important and well done.
-Story-
Not much has happen so is a bit hard to review this aspect but I'll say the prologue is a good start and creates a good intrigue on what leads to those events. I notice you planting or foreshadowing things which is a good setup (the hair, the skylar's family issue). I'll have to check it after 10 chapters to be able to give a better view on the story, but for now it seems interesting.
