Hi I enjoyed looking through you photos as Greece was one of my favourite travel destinations. Sadly it may be some time before anyone can visit there. For the Get Pushed 445 challenge I'm suggesting you take a photo of a single object with a shallow depth of field. There is a lot of information on the internet and examples of photos with a shallow depth of field. I look forward to seeing your photos.
I especially like the way the guards march with their legs way up in the air!
