Catching up....seems I've somehow missed all your shots, so here goes.....
Gate-I prefer the uncropped version, works well
People-bit busy for me, but works for the theme.
Stark-I really like this, though I prefer the mono version
Over-A bit too grainy for my tastes, but it works
Age-I prefer the second one, mainly as it has more contrast
Sharp- a good sharp shot of sharp claws. I'm not so keen on the oof cloth in the foreground, the second crop works better imo
Guard-A nice abstarct imege, but a bit difficult to identify if you don't know what you are looking at. I really like the mono one taken with the Hasselblad, though again, it's a bit difficult to work out what it is.
Thick-I prefer the colour version. On theme. I took a very similar shot myself a few years ago.
Abundance-I feel it could do with a bit more contrast, and it's a shame the river is hidden.
Heavy-I agree, the framing is a bit tight, and again, I would have gone for more contrast. On theme again though.
