I have extensive experience in creating custom terrain and maps, including export with mod specific blocks, up to 16k x 16k blocks. Call it self-advertisement/pride, but I'm confident in my ability to craft a base map in a timely manner. I will use my cancelled project as support for my 'resume'.
With my current Pixelmon map nearing completion I can divert attention to helping the team & community with this project in a significant way involving terraforming (if I may of course). I'll be away for two weeks directly after Christmas (Specifically 27 DEC - 9 JAN) but if there's anything I can do to help out with the terraforming of the world, please let me know. I am very interested.
Edit: Should have included this earlier. Would the region have its own, special town with an architectural design separating it from the rest of its peers? What I mean by this for example, is that Ecruteak had an Eastern design that separated it from the majority of Johto. What would the specific architectural theme here be if chosen to have one?
