The way I did it was by opening them in separate windows side by side, zooming both pics and then observing the images in their depth of vision. I felt No.1 was sharper, because:
1. The tree branches down the centre path seemed blurrier on No.2
2. The sunrays in No.1 seemed brighter
3. The distant shadows in No.1 seemed sharper, though the nearer ones seemed appealing in No.2
4. Vegetation next to the hands is blurrier in No.2/ sharper in No.1. Same with the vegetation on the right side, next to the tree
But then again, I wear specs!
