I'm just trying to solve the shorts problem, not reinvent the wheel. I'm still not sure whether it looks better to keep that other section of yellow going around the back of the waist, but I decided to keep it for now.
A few extraneous lines on the boots aren't hurting anything. Shut up.
EDITED TO ADD:
One thing I feel like I may toy with is bringing the upper red bits closer to the center and maybe even converging at a point above the "buckle" on the belt.
