None taken!
In addition to learning all the tools at the same time (including graphical tools like GIMP) I'm also trying to do a few things that I haven't seen done in the current maps, which has added considerable time to the process. Laying out rivers has been especially time consuming, especially since each and every grid cell junction about has to be massaged by hand.
Not to mention, I've done a lot of it on the train on my laptop, which means that for every hour I work, I get 20 minutes of "real" work done (were I doing it on the desktop with a real mouse and something larger than a 8 inch screen). So with all that in mind, I've spent what would take me about 40 or so hours to redo now that I know how to use the tools
And I still have a couple of things left to do before I submit.
