Some things I've learned from this illustration:
1. I can work very fast (research, sketch and final artwork made only at 3 hours)
2. Being lazy and let your work for another day is the worst idea you can take (work now or never)
3. Music is very important to get a rythm meanwhile you are working.
4. if you work for other countrys you have to get familiarized with the time zone.
