Simon, they are perfect and finished just in time since my PCs found the tunnel entrance last night I build a full escape tunnel map in D20Pro using this tile set from Neyjour. I will try to upload, just as soon as I figure out how to get it out of the program at a nice res.

Once I finish writing the rest of the adventure I'll post a copy for use.

Thank you for all you hard work, I really appreciate the effort you put into it, and happy to donate to help keep this site running.
