But I only check the tutorials every couple of months.
The trouser looks good except for the seat.
#1 removes cloth at ths waist and tapers off to zero at the seat.
The alt on your trouser is #2 in the reverse of #1. It removes cloth
in the seat area and tapers to zero at the waist not taking in anything there.
caution do not make the seat too tight, as the side pockets may gap.
