@Xan09 strange font at the start of first page, I'm not sure it was needed to pick such weird one; in many bubbles text is too close or even touches the borders, which makes it hard to read; text on the phone screen, on the contrary, too small and impossible to read with "fit height" setting on my screen, plus, you put one of messages over the girls finger; vertical text on two last pages is unreadable. In general it's rare case when vertical text looks okay, and one has to choose good fonts for it and all, but I think starcream managed better with last page. Still, vertical text better be avoided.
Also, after putting your and his scans side by side aligned with same height, I noticed your scans are more blurred, especially in the first half. That's strange, if you have bigger dimension, you should have better image quality.
