Here's mine currently. I haven't done too much terraforming other than around my campsite and secret beach, a little bit around my house, and some slight adjustments to the river shape on the right hand side.
Not really too sure what the end goal will be. I'm not doing any major planning, just adjusting things as I go and seeing how it looks. I'm mainly trying to move around villager houses and bridge placements before i do anything else major. also still need a 10th villager
