IMHO, the second and third are the most successful, perhaps because of the isolated subject. I like the B/W rendering, too.Keep shooting 
Despite how it sounds, it's a serious comment. You'll find it if you persist. Good luck.
I think David said it well: Keep shooting.
...
Thanks you both.
The problem with "keep shooting" is that I have little time to shoot
(sadly) and that I still trying to understand exactly what I felt in that place.
When I went there the first time, what struck me was just the beauty of the scultures and the peace of the place.
But during the visit I walk around the corner and went to the "children sector", with its rows and rows of niches of children of any age.
1906-age 7, 1903-age 4 months, 1912-age 12 and so on for hundreds of niches.
That's when I start thinking about how those people related to death: today death is a tragedy and something to subdue and control, even when is a choise
(like in euthanasia).
But, for the people in the 1900s, death was a daily occurrence at any age.
Maybe, I thought, all those scultures were made not as a memento of the deceased but as a rebellion against something they cannot fight, a way to say to death
"you got me but you'll never get what I've been".
And, while thinking about it, more thougths came to my mind while looking at the scultures.
Thoughts like
"Was the fall from heaven a punishment of a gift? What would we be if we were immortals? Would we be making art, music, sculture if we have all the time in the universe?So I'm still wrestling with these thougths and I'm not sure that going back without sorting some of this stuff out I would get better images.
