The lighting in this image is very dramatic. The subject matter of the silhouette is hard to distinguish and might be improve if shot from a slightly different angle.
This is one of those shots which have benefitted from some fill-flash.
It's lacking in detail for me.
Otherwise it is very nicely composed, with a great choice of angle to get in and get the shot.
You've clearly thought about what you wanted your viewer to see.
I like it.
Good luck!
The sky has great color, and I like the effect you were going for; the statue is a little hard to make out though because of the figures standing around the cross. If there wasn't a title/caption for this photo it would be difficult to figure out what the message is.
