Welcome to the USNW, Steve, I'm K50, one of the executives here. Just so you know, You're going to be applying for Ambassadorial Membership, you'll be able to do much more... plus we don't really accept new observers anymore
You've got a nice start, but you're going to need to do a few simple (but possibly tedious) things first to confirm a spot from most of us. First, I'm a little confused by the location. It looks like you've chose multiple spots, which is okay, but I can't tell which one is the the mainland. I'm guessing it's the one at the top left, correct me if I'm wrong.
Second, and this isn't a huge deal for me
at the moment, but you're without a doubt going to need to do this eventually, is custom content. You're going to have to go all-in finding buildings from SC4devotion and Simtropolis for your future pictures. The biggest issue for me are a few realism issues, that hill on the first picture is sort of a mess
(I liked the idea of the tunnel a lot though.) so looking at city journals, especially those here, is a good idea to get some ideas, and I think you'll be inspired to pull off something very unique and something that could happen in real life, which is the ultimate goal in SimCity.
You might also want to add history, as in, when were you established, how so, and how far you've come. Demographics are also important, we want to know how big, rich, and who the residents of Goat Rock are.
Finally, no offense, but the name "Goat Rock", well, I'm not hooked with it
That sounds like a great name for a city, province, state, district, island, etc., but I think for your country you can do something more unique. You used one name, New Fivos, that sounds like a much better name in my opinion
Sorry that seems like a mouthful, but I think a few improvements and additions could get you well on your way to an ambassadorial membership, and I'm looking forward to seeing what you can do
Welcome once again!
