Hi everyone,
I think many players are already bored of seeing the same background all the time, it was nice in Christmas when the ice falls on the village.

I would suggest why don't you make the 4 seasons backgrounds, day and night too, that would make the village looks awesome specially when the fire of the advanced walls and army camps appears.

I suggest some volcanic backgrounds too and some rocks thrown from the volcano to the village so we have stones and trees as obstacles to remove.

maybe background for each Town Hall level.. so volcano for sure for th10, bones and dark stones for th9.
I would suggest different colour for town halls from 1 to 8, th8 maybe golden town hall for instance, they are all looks the same, you can add some red blue or purple colour for the rest.

th1 and the can be brown wood.

those suggestions will make the game look better

Cheers.
