I like the natural expression in this one in both your body and your face.
By comparison, you have a vacant/blank sort of expression in many of your photos.
There is lots to like about these two photos, but your expression (face and body) seems somewhat reserved/tenuous.
I find many of your photos to have the same half-hearted/tenuous/unengaged expression. It is unclear the emotion the photo is trying to convey.
I much prefer this expression and pose - you seem much more engaged in the photo and this gives it life.
The truck and tractor shots take away from your portfolio in my opinion.
This one just looks like a holiday snapshot (not that anyone takes holidays in Pakenham).
I hope that's helpful.
