Funny to read your description Nick as from the thumbnail I thought this was indeed one of Janet's.
It's a well assembled image and obviously very personal to you and your family. The narrative does indeed make for a most interesting read ..... brave young men one and all just born in the wrong place and time. There but for the grace of god and all.
The background suits the objects and theme really well but if I had to niggle (and I know you would expect nothing less) then I'd say that for me the framed photo is a little too square-on to the viewer. Angle it slightly away from the viewer on an oblique and this IMO would look more convincing and add depth to the image. Also, to me the goggles don't sit too convincingly on the frame .... they look superimposed rather than actually hanging there in real life. That said I can't quite put my finger on why they don't look quite right. Maybe just angling them away from the viewer would help in this respect too?
