Model AI lebih paham instruksi teknis daripada ungkapan metafora puitis.
Satu perubahan per iterasi. Kalau hasil sudah 80% bagus, jangan ganti 5 field sekaligus. Ganti lighting.color_temperature saja, atau camera.lens saja. Ini sama seperti debugging.
Subject dan camera selalu letakkan di awal.
Hindari kontradiksi. Meminta background: minimalist tetapi ada banyak props, akan membuat model bingun.
