This is a charming shot. Beautiful b&w conversion. Looking down into the fenced off yard is an interesting take on the 'hidden' aspect of the challenge.
This image lacks a interesting subject. There is a lot going on but nothing that really captures my eye. Those trees are blocking everything in the background. Technically it is good and with an interesting subject, like a big house, it would do a lot better.
Wow. The B&W treatment, plus the non-descript houses (no cars in sight), give this photo a nostalgic feel. It would difficult to put an age on this if this photo was just presented to someone randomly. Kinda cool. :-) Good luck in the challenge.
