This is a rough guide how this drawing came to life.
1. Sketch number one. Legs are missing - appalling. (Human age equivalent 0-1 months old)
2. Sketch number two. A potential, needing refinement. (Human age equivalent 1-12 months old)
3. Refinement in progress. (Human age equivalent 1-5 years old)
4. Inking complete with extra thing happening on the side. (Human age equivalent 18 years old)
5. Colors done (above), and extras etc cleaned up. (Human age equivalent 21 years old. After that it's not growing up anymore, just ageing).
