First off, I want to say hot damn you've put in a ton of work on this over the past several years! I am blown away! I stumbled in here chasing links from roll20 and needless to say, you've put a plethora of tools in my hands to improve my map making!
I noticed in the first post you had a link to a page to be able to download a zip of your creations, but that link is broken.
Navigating to the host site, their link for the gimp/photoshop version of the collection is also broken. XD
I'm curious if there is an updated link somewhere that has all the files. :)
