Welcome to the Guild Sinathor! Sounds like an ambitious and worthwhile project. I wish you every success in it. As far as gleaning tips and tricks regarding the creation of your map, I would suggest spending some time in the Tutorials section. There are tons of great walk-throughs to be found there. You might also wish to check out the Finished Maps section and the Regional/World maps sections to see what other Guild members are working on. Not only will this exercise offer you a good bit of inspiration for your own project, but it will also help you to glean map-making tips. When you do begin your project, I'd recommend starting a WIP page and asking for feedback. This is a great way to garner constructive criticism. Anyway, look forward to seeing your work.
