the second you havent composed it very well, with him looking out of the frame to the left you’d want a little more negative space for him to look into, he is too centered.
the third is nice, but you have boxed his head in top and bottom – looks awful
The third image for me though the crop is a bit tight particularly on the chin if you had room on original you might try a different crop. On the second image i find the contrasting shadow/highlight between nose and left eye area a bit harsh
