Greetings from Andi via the Critique Club and congratulations on submitting your first entry here at DPC!
First Impression: The 'footwear' fills the frame nicely and a nice touch adding the snail which adds interest to what could easily be a boring subject.
Composition: The square crop works for me here and the centered snail works well.
Tecnical: The Snail is well lit and the oof backgound works well to keep the viewer looking at the subject. Good focus where it needs to be sharp and I'm loving the in focus line along the ground.
Artistic: The sole of the shoe is a little dark on my monitor however whilst it might have hurt you slightly in the voting the more I view the image the more it works for me, the well lit snail is being encompassed by the darkness of being trod underfoot (thats deep for me).
Overall thoughts A fun take on the challenge theme and a more than competent entry. after viewing this for a while I'm now being drawn to the white space on the right of the image and its distracting me slightly. Gave this a 6 during voting btw.
