I've just skimmed through it, and I have to say I'm very curious of what's going to happen next. It has great art and suspense, the panels are very organised and spaced out nicely, and I wasn't confused about which panel is next.
The text is big enough for me to read comfortably too, but I notice that sometimes it was reduce to 1/3 of its usual size. I recommend that you keep the text size consistent, since the smaller size is a little difficult to read.
Good luck on your comic!
