I really enjoyed reading through this adventure, enough so to use it in an upcoming game. The town is extremely well fleshed out with good details on structures and people. The story/plot for the adventure itself got more and more interesting the further I got into the module.
It is also quite simple to convert for your own campaign setting -- while this adventure does take part in its own world/lands, I found very simple to modify for my Forgotten Realms game and it fits in quite nicely.
The maps leave something to be desired, as they look rather simple and crudge, but they get the job done. Artwork is a bit sparse and not overly impressive (some is way too low resolution), but it isn't a big problem. The pdf is pretty printer-friendly too with only a very thin border.
Anyhow, if you're looking for a really fun first level-module that is easy to fit into just about any campaign, I highly suggest you take a look at the The Mines of Medgorod - I thoroughly enjoyed it.
