It seems to be a nice image . It would be better to see it in a larger size to make further comments . BTW, welcome Alekos My ancestors on my mother's side were from Crete Island .
As you will see, I have linked your image into the post. Please do read the helpful guide that walks you through how to do it. Click HERE to read the thread.
Welcome Alexos. I visited Athens two years ago and really liked your city.
Your image is a wonderful slice of life. The only slight change I would make if it were my image, would be to crop the left side of the image slightly to remove the portion of the arm jutting into the image...
