The Mood Grid has saved me a lot of time, when I have my ideas and concepts in order I don't need to waste time on rough sketches trying to come up with a solution.

In this case I already know that the objects I need to illustrate are: Nature, Sustainability and Time. That the values are: Equality, Diversity and Solidarity. That the place is the planet earth and that the people must be those who are usually underrepresented.

If you are wondering why black lines and red lines, well, there is not reason, sometimes I just delete a black line and make a new one in red to see a clear difference.
