it is too difficult to critique these all at once.. there are 13 here.. split into the categories we use -- NCAA football.. NCAA basketball.. other....
as for the sports cuts
#1 - you cut too deep on arm - there's like a gap where his arm meets his leg. also, there is bg on the facemask in places
#2 - appears to be some bg left between ball and arm
#3 - BG in facemask. left arm choppy
#4 - arms are bumpy - needs some smoothing out
#5 - it's R.Mendenhall, not Williams
#6 - tad BG in shoelaces -- best cut of the bunch
#7 - low quality pic - but great cut. it's J.Williams, not I.Williams
#8 - top back of helmet needs rounding off. it's J.Williams, not I.Williams
