Does one mushroom is enough?
How do you define " something creative" and "something arty"?
Kite Kraemer: I really like this one, wish there was some backround detail, or even straight blue sky, but this gets my pick.
The day when the picture was taken the weather was so-called whiteout, then a contrast was reduced by white clouds merging with white snow. So a blue sky background was not possible. I like to shoot with this light, but it's challenging not to underexpose the object. Thanks for your comment.
This picture is from Finland, on the top of Muovaara in Kuusamo about 100 km south from Arctic Circle so not very far north. There were big forest loggings about 20 years ago. This explains the size of the trees.Thank you for your interest.
One of your additional rule " Ordinary birds like pigeons and sparrows are not allowed" is a litlle bit confusing. IMO seagull is quite ordinary everywhere.
Yes, the plaza at the Rossio metro station.
Are the other alternatives accepted, for example summer and autumn?
I tried twice, but the votes didn't fix. It so frustrating to waste your time in voting.
