Good story, well laid out, with a nice few hooks in there, so that we want to come back for the next one. I'd suggest that you research the layout of comics and make this one more of a "comic book" style layout, rather than a thin strip that descends down a page like at the moment. I'd suggest Order of the Stick as a basis, since that is laid out horizontally, with as many frames in lines below as are required.
I love the black and white of this - it kind of reminds me of old Beano or Dandy issues (showing my age there!), when they weren't all printed in colour. The one difference is that this sets the tone for something dark and mysterious. I'm intrigued along with the story as to how this will turn out.
Perhaps in an introduction issue, the walking down the stairs took up a little too much, but as we look at it for now, you've drawn each frame really well and the setup does kind of work. You could see to lose maybe three frames, without harming the integrity of the piece, thus leaving a little more space for plot exposition.
Could you leave it on more of a cliff hanger? Perhaps as she leaves the cafe with this mysterious old guy, who is asking her if she believes in magic, something is said, that makes the reader think a little deeper, while they wait for the next issue?
