Your comic so far is serviceable, but While reading it i felt like your potential was not really being displayed properly. I mean you have a wide appeal art style with only really a few glaring weaknesses (will touch on that towards the end) , you have good solid character designs and a fun imagination.
But the focus and pacing of the plot needs work.And ill explain what i mean.
The focus and pacing suffers mainly due to irrelevant scenes and odd choices from the MC. For example when she wakes up and she sees the mirror and you can see in her face that she recognizes it from the dream she just had. And then she just says "whatever" and uses the restroom, which sort of seems like a odd choice. You did a great job expressing the sort of shock /confusion and possible fear in her face to just kind of toss it a side for a quick potty break. I feel like you could of used that scene to really kick start the theme for the rest of the story.
And then we have her encounter with the Robot, and instead of it being kind of a meaningful experience (since it's a talking robot) it's more of a underwhelming one since Josie honestly doesnt seem surprised by it. Which weakens the weirdness of the event since if Josie isn't really feeling any strong emotions about this why should I?
And sort of the most confusing part for me is the fact that after she accidentally teleports the robot away, she suddenly wants to teleport herself? when did she decided this? why did she decide this? what does she hope to achieve by doing it? If its just pure curiosity I would argue that you didn't really show that side of Josie's personality well.
And even though we are 4 chapters in all we really know is that "E" wants the mirror that Josie has , we dont really know why Josie wants to even keep it from her. Now I understand if you wish to keep certain plot points secret (obviously) but you still have to give things a reason for their actions and so far Josie doesnt seem like she has any. Those are really my main gripes with the story and i think they can easily be fixed with just a little more patience and thought on your part.
And I said that I would Bring up the few flaws I saw with the art but I kind of made this longer than it has to be already so ill make this short and sweet. its honestly just the hands and sometimes the legs, but mainly the hands. i think it would do the comic good if you worked on drawing hands in a more dynamic and most importantly coherent way.
With that said I really think this has potential to be a cool and fun comic and I really hope anything I said can help down the line.
