Lovely story - loved the original series - this does feel like it ended to quicky without any complete story. The sharing of this is also individual downloads for individual pictures so that is a pain - and ordering is hard since naming conversations are different.
I would increase this to 4 if it was either renamed correctly and added to a individual zip file (or one per chapter) or converted to PDF. I would raise this to a five if in fact it had a ending that felt like a ending and not a "over it now" :D
I so wish to see this story continue - there is a lot of VERY awesome places this could go.
