help with height!

[mayor.lauren]

hi everyone! so i'm working on terraforming my island, but i'm having a bit of trouble. i'm trying to make a nice large cliff section in an area where i have quite a large section of land to work with in order to get some height to my island, but everything i make looks kind of blobby and not quite right... would someone maybe be willing to help me out and give me some advice on where my cliffs could go? i circled the areas i'm looking to add height to in red (bonus points if you could maybe help me draw it out so i have a guide to follow!) i don't have much, but would be willing to pay in igb, nmt, or tbt for some personalized help! thanks!
