Hi Antonella, your painting has a nice mood. You have all the technical skills, to paint wonderful pictures. May be a little bit compositional thoughts would help.: What is my focal point, what is the structure behind? Which way should the eye of the observer go? You have your strongest contrast in the hard edge of the shadow in the foreground. Is this the focal point of your picture? The dark wall on the left side distracted me, it closes the picture… thoughts like this, would help, i think.
