which island should my next map take place on

heresa back story from my skyrim mod which i made i lost it on one of my old computers when i find it ill show some screen shots

shifa (black flag)
it is a tropical island with underground caves that run into the sea
it is owned by shifa

zakhi shifa (blue flag) this island is owned by shifa and zakhi
it is a massive desert with high mountains and not much water

zakhi (orange flag)
a small island about the size of Upolu x3 (3,100 km²)
its a cold island with breathtaking mountains


ivelabled where my last map was scale is not right but ill just rescale the island to suit beamnga bit better
if i can figure out how to place multible terrains it can all be on one world

 

If this is for skyrim it should be in https://www.beamng.com/forums/other-games.41/
