As mentioned, we want you to create a new postcard for us. But not from scratch. We found a nice design in another country and we want you to adapt the style of illustration which was used there.
The main sight which is supposed to be in our postcard is the Berlin TV-Tower (GER: Berliner Fernsehturm), along with the typical blue entrance-sign of the Berlin subway of the square where the TV-Tower is located -- the square is called: Alexanderplatz.
Place the sign as shown in the pictures, maybe with stairs or without - whatever you think looks best.
As in the uploaded example postcard, you can use some green to cover up free spaces --> Berlin is an extreme green city, so this would make sense.
Even though there are other buildings in real life standing next to the TV-Tower, in this postcard NO other building should be illustrated next to it.
The mascot of Berlin is the Berlin Bear (GER: Berliner Bär) - as in the example postcard, we would find it funny if the Berliner Bär uses a parachute to glide from the sky --> attached you find an nice looking illustration what the bear could look like.
Your are free to place clouds, sun etc. in the sky if it makes it look good. Please do not place things which are not common in middle-europe. For Example: A palm is not common. :-D
