Overhead View of Teaching Garden

A Los Angeles charter school committee is interested in converting an little-used parking lot into an educational garden. Here is the concept illustration I produced for their fund-raising campaign: 

Initially, the committee and I discussed how to best illustrate their ideas, exploring the option of illustrating each feature. Here's the preliminary sketch showing students working amongst the raised vegetable beds:

But we decided an overhead view would more dramatically show the transformation from dreary asphalt to vibrant garden. Here's the preliminary sketch I drew of the bird's-eye:

The committee then directed revisions (more covered lecture space, an exit gate, etc.), resulting in the illustration above. Let’s hope this generates a lot of interest and the necessary funding!
