how to rockscape a 38 gallon tank

[LifeOfAquatics]

so i have a 38 gallon tank with the dimensions of 36 in length, 12 in width, and 21 in height. i am unsure what i should do for rockscape since the tank is rather narrow and tall. any ideas? planning to be a reef tank btw.

This was my 38 before switching to a 40 breeder. It was too narrow for my taste. Tried 2 islands first, but it ending up as a wall in the end.
