interesting shot! All comments are good thus far a good.
personally, the middle row of coffins are a tad to aligned in the center for me, though it doesn't really make that big of a deal.
The cropping people out is a good suggestion, if you want to emphasise the coffins, and its definately a good choice for this pic because the people are in the background.
What would be interesting to me is to see how people interact with the coffins, sort of the mix of the dead & living. Do you have any more shots from the day?
