The Emerald CityLogo Design Contest

We are having a 'Wizard of Oz' themed fundraising event and the title is 'The Emerald City' (main imagery is the building and yellow brick road, etc...)

Green as the primary color for the building.

EPS (vector artwork) only.

These are the elements needed in the logo: School Building (attached JPG version to be simplified for logo), yellow brick road, plants / nature along side of yellow brick road, rainbow over the school, hot air balloon flying (with a large "H" on it), Title "The Emerald City" smaller underneath the logo

Considerations

1) The school building needs to be green but the surrounding area does not. The natural world along side of the yellow brick road should be represented in color (e.g. the plants can be green, purple, red, etc…).

2) I would like a feeling of perspective for going a long way to reach "The Emerald City" (our school building).

3) Logo should be able to be used for Letterheads, invitations, screensavers, etc...

4) Reference to Type Style... http://thewizardofoz.warnerbros.com/ for "The Emerald City" that would be under the Building logo.
