A line drawing with watercolour enhancements, illustrating the process of domain registration transfer within a registrar. The sketch should display three distinct touchpoints of the process. The color palette should be composed of gentle, harmonious colors, suggesting the serenity of a smoothly enabled process. The whole scene should evoke a sense of calm and efficiency with limited hues, focusing on the steadiness of the transfer progression rather than the vibrancy of individual elements. The illustration should be simple and soothing, capturing the tranquility of a well-orchestrated process.
