That's a lovely place, but the scene you choose is boring. Two folks on the left are turning the back on us. In the foreground there's nothing we can focus.

 

Try to put some children with an animal etc. in the front or yourself.

It's a nice spot to shot a photo, but the low clouds are stealing the sunlight -- and so the good mood gets lost. Dealing with bad weather: better take some detail shot than a perspective.

As it got discussed by Raymond and yourself, Maria ... Your photo tries to present everthing mentionable of that very fine street szene. Everything is "nice", like the clock tower, the balconies with their balustrade, the picture sellers on the right, the statue in the back. But everything has to compete which each other. So everything loses some of it's magic. You should indeed present serveral pictures -- one which shows the street with all objects of desire (maybe from an elevated viewpoint), and several others each emphasizing one detail. In my opinion, a busy street makes a picture more appealing -- you just have to await the perfect moment! :)

I'd rather wish to get the water play of the fountain in more detail, clipping those plain benches at the right. So you'd stand some feet to the left, nearby the fountain. Think about it the next time in Lisboa, Maria :)
