Overall, totally awesome!
I cannot say enough great stuff about these pieces! They have served as a spark, and set fire to my imagination.
-1 for learning curve. I'm relatively new to isometric dungeons, and I got this set with the hopes of using it in my Roll20 campaigns, which meet every other week. However, getting the pieces to line up in GIMP and then convert over into a map has eaten up ALL of my prep time.
A Read Me file with info on how to adapt to Roll20 would have been fantastic.
