Kestrel,

I'm glad you like it! I didn't keep a precise count of the time invested in drawing this up, but I was able to listen my way through quite a few albums and "Let's Play" series on Youtube in the process, mostly because when working on a project like this, I am very neurotic about verifying my calculations multiple times. One thing that helped me a great deal was taking notice of a few patterns that emerged after several calculations that spared me a few steps for each point thereafter.

I am aware of G.Projector in a limited way, I've not actually used it, however, so I'm not familiar with its capabilities. I may have to look into this. Nevertheless, I hope this will prove a valuable resource for people who like to create their maps entirely in mainstream graphics editing programs!

Thank you again for your kind words.
