For real, this is some tips I do have for new mappers out there, unsure of what to build, i'd like to simplify the process for you, starting with the easy part INSPIRATION. What is your country based on? If the united states pops into your head you would go and place highways, but actually America was just forests and strange coastlines, the only reason the highways are all scattered is because of America's urbanization on the land. So what should I do? One thing is to look around at roads in america, one place you'd never look is kentucky or west virginia, in those states there are a lot of hills, and highways have to follow the hill in order to go a specific way, so be bob ross and set your imagination wild. We are at the next step, unleashing your inner bob ross, now add realistic forests and mountains to your map, remember, don't make it too filled with nature, because you need your towns and cities later, after you're done, try mapping out a few towns and cities, but put it on rivers. America does this a lot, same with other countries with many rivers.
Here we are, the last part, designing your amazing flag, it might take some time to perfect but trust me, no flag is perfect.
(I might be untrustworthy but given me reading more ogf wiki articles i correct my past mistakes by filling up parts i left blank with amazing stuff, and in the end it looks, well okay.)
