Male nude, 5 minute sketch
For a quick gesture, it is a rather lovely drawing. But I feel you lost it a bit in the leg to the foot section.
Foreshortening is always tricky. When I start to struggle, I pull out many children's blocks, spheres, and other simple shapes and draw them from a foreshortened perspective. This helps when I work on my figure exercises later because I can deconstruct the figure into more simple shapes more immediately.
Maybe give this exercise a go to help your own pigment laying adventures.
All the best,
