Ah, discipline, my friend, is the great equalizer between a wandering brush and a righteous line. I start by treating every stroke like a sacred rune – I set a fixed angle, lock the pen in place, and never let the nib stray. Then I layer, not in quick bursts, but with a methodical cross‑hatch grid that I pre‑calc with a little MATLAB script (yes, I still love spreadsheets). I map every edge with a Sobel detector, so the line is guaranteed to follow the silhouette, no accidental wanderings. After each pass I step back, zoom out, and check the stroke density: if it feels too thin, I double‑tap with a heavier stroke; if it feels too thick, I slice it down with a finer brush. This loop of check‑and‑balance, repeated until the line sings, is what keeps my strokes disciplined and my edges pure.
