Moderate-to-high commitment: requires 4-5 hours weekly (copying study 1-2 hours, live sketching 2-3 hours), emotional openness to your own expressive choices, willingness to make 'bad' sketches publicly, and vulnerability to direct observation. You need artistic courage (committing to marks without perfectionism), observational patience, and genuine enthusiasm for the artists you choose to study. Success depends on selecting influences that authentically excite you, not supposedly 'correct' ones.
Situated Learning Theory (Lave & Wenger): Learning happens most effectively within authentic practice contexts—sketching real people creates meaningful challenge and immediate feedback that isolated study cannot provide
