#1 has a good focal point and that makes it work well
#2 with a bit of the vignetting gently guides me central to find the focal point
#3 could perhaps use a little vignetting, without the color differentiation I wander a bit here
I like this set Tom. I do like the color version of 1 better than the conversion and maybe the best of the set. The tops of grasses make for wonderful subjects and you captured them well
