Map ideas.

[Kaos1559]

Ok so Ive been working on a custom map for some time now. This map is going to be where you need to collect every player head I have scattered around the map. But your able to destroy terrain like spawners and such. So heres the thing i'm fresh out of ideas. So if you could say below what types of areas I should have and like what difficulty level I should make it that would be very well appreciated.

Make it-

Snow- hardest, hence Ice and Snow that could cover blocks.
Desert- Easy, flat discluding sand dunes. Have Sandstone caves scattered about with treasure
Forest- The hardest of the Hardest- Too much cover, make it dense, maybe a jungle
Field- Hard, easily coverable by longgrass
