Can you please tell in which city the story is taking place around? Can use the cityscapes as an element,

The story takes place around Sydney, Australia. Yes, you can use cityscapes as an element, but don't make it too tourist-like or too prominent. Thanks.

I entered once and if you could mention what was missing from the entries the last time you held this contest, it would be very helpful and might encourage me to enter again.

If you can send me your design again, then I will gladly comment. Then you can send in a new version, etc. Jon-Claire
