Thanks for all the comments so far, any critisism can only help me improveI do find it a little soft and I'm wondering if your choice of f4 is perhaps the cause; with an egg being particularly famous for not being flat I'm thinking the depth of field at f4 on 105mm a bit wide.
This is the kind of feedback I like, to be honest the choice to shoot at f4 was to help hide a few of the creases in my attempt at a mini home studio setup, the first one I have ever tried to add.
Interesting choice of orientation, why did you choose to shoot this landscape rather than portrait?
I had already laid out a set of rules for myself to follow, one being to keep all my my52 photos the same orientation, just to add to the challenge.
I'm more interested in why you like this shot and what you have learned this week but taking this shot.
Your first point regarding a the shot being slightly soft, it's something I shall experiment with next time I set up a shot like this. I know having the lens at it's widest isn't the best way of getting a tack sharp photo but the bodged attempt at a mini home studio outweight this. As it turned out with a little editing the creases could have been lost anyway so this is one lesson learned!
As I've suggested to another egg shot have a think about how you could develop the idea further and what you might do differently if you chose to RESHOOT this when a RESHOOT card is drawn?
One thing I would consider in a reshoot is what colour background to use, perhaps try a white background and light it in a warmer colour. Make it seem more alive almost.
