Story? Nu-uh, pick it up and you will know. Best, but I think it's best to keep it short like this, as a one shot.
For the art itself, the author really know how draw atmosphere so the reader can really feel the adventure that the heroine have been. It's beautiful, nothing more.
Enjoyment? Slow pace but leaves you good at the end.
Overall? Pick it up. It's really good. It's one of the best one shot I have ever read.
