Thank you all for your usefull comments. As said tarique, he is just cleaning, every contest is a challenge (creativity and imagination). I try to see all around me what can be applied to the theme, sometimes it works, sometimes not. Anyway it is always exciting.
And I will try, thanks to your usefull comments, to do it better.
Composition isn't the most interesting. The picture teases you with a little lawn, a bit of flowers and some bricks at the top. Maybe a different angle instead of vertical would help.
