Heaven & Hell idea

Contest based on a small map featuring heaven and hell theme.
Heaven - An custom 4 holy heroes with custom spells, and Heaven terrain and map look.(grass,bunnies,etc.)
Hell - An custom 4 evil heroes with custom spells, and Heaven terrain and map look.

The idea is to post maps and vote for the most contrast looking maps. This would include map terraining, creatures, doodads, heroes(the more contrast the better), and spells with half heaven half hell look.
This may but doesn't include modeling and skinning, and doesn't give extra point for the modelers and skinners if they use their spells.
The main point is to create something refreshing, not just use Death Knight with death coil as your hero, all heroes must be custom, with custom spells. Events like meteor shower, healing rays, and such give bonus points.
On the end map that shows the heaven and hell the most better wins, in that criteria maps are judged seperately, first the heaven look, and after that the hell look.

May not be the best idea for the contest, but it is at least somewhat original.

Sounds interesting, but quite difficult to make, it would require team work

Well, then why not make it team work?
One team can have 3 members(example - 1 terrainer, 1 spell maker, 1 something member), or just set an locked map size, something smaller not epic.

Then it should be Paired Map contest, but one Paired Map Contest is already on Paired Mapping Contest #4, but this could be a good idea for the next one I suppose

This wont work. You're getting way too specific. 4 heroes, must have custom spells, must have heaven and hell, etc. You need to give some freedom.

Hmm, no hero limit, but contrast needed(example 1 good 1 evil hero), also no need for trigger spells but they should be custom.
