Well it's a little hard to evaluate writing quality from this early on in a comic, but so far it's looking pretty good. You get right to plot in the first few pages, which I like, and manage to characterize the shadowy looking guy a lot through his movements (The way he looks at himself in the mirror and trips down the stairs). I think my main critique is that the girl and other guy (Margo and Travis?) have very similar ways of speaking, so maybe you could try differentiating their voices some more?
Also, there are several typos I noticed (page 10 panel 2 "your" > "you're", page 10 panel 4 "flushing" > fleshing",page 11 panel 4 "resently" > "recently") You should double check your speech bubbles or have a friend look over them.
Despite these issues, it honestly looks pretty good so far! You have an interesting and competent beginning, so I just hope you can keep up this quality til the end of the chapter!
