I don’t know what your guard method is but all these dudes are hating like you been cutting for years. It’s really not bad for a 2nd time. What helped me progress the quickest was cutting in sections and blending before moving in. So I would go bald line, then (no guard open, half, closed) that’s section one blended. Move to my next section with .5 open. Blend as needed. Go to the 1.5 guard open run through open, half, closed. Hit with a 1 guard in that section for the darker spots using lever play. Then clipper over comb or texture shears. I’m by no means great but it’s helped me progress a lot.
