In terms of story, I like what I've seen so far. I think you should aim to bring out the end goal of the series as soon as possible (which is probably what you are trying to do). You have a great way of writing mystery in a way that doesn't seem forced down the readers throat, it almost reminds me of one punch man.
The line art is very nice I liked it! Something I'd say on the anatomy side of things is that the characters seem a bit stiff and the proportions are a bit off. But as you settle into drawing the rest of the series it will definitely improve. I found the hair unique but at the same time I felt that it got a bit in the way of the story being grounded. If this is what you are aiming for then that's good or may just be me being nit picky. Apart from that the art transmits the actions well. One thing I was thinking about which isn't necessarily bad but I think could increase the impact of the comic is instead of putting "sfx : sound" or whatever sound effect as a side note, make it almost part of the comic like this...
Once again, different comics, different principles so you have to see for yourself if it will work for your comic.Characters
Your character writing is fantastic! Olivia was a very endearing character and the other characters as well. I don't know if English isn't your first language but I'd just be careful with checking grammar. Of course it's not the biggest deal but it is something that contributes to the quality of the reading experience. If you need someone to spell check and such, feel free to pm me and ask, I'm always free to help.Conclusion
I really liked the comic, it was quite relaxing and the characters were nice! Maybe one final aspect I thought would be good touch upon is exposition. Exposition is okay, but I find it interesting when stories are able to give information through more subtle ways. For example when telling us about the name of the school or the apartment, you could show us Olivia walking through the entrance and we are able to see a the nameplate of the building which shows the name, just an idea. I give this comic a 7/10, Thanks for your submission my friend.
