Where are the children? (Pinhole)

This is the shot I submitted to Pinholeday.org for the WPPD 2013

On the grounds of an abandoned primary school. Shot on World Pinhole Photography Day (WPPD) with my DIY 4x5 pinhole camera on 120 6x9.

I particularly like how the goal posts seem to glow, almost a halo effect. Strange since Acros does not lack an anti halation layer.
