Logo design for Habitat Hero

My charity client is working on a regular giving program to raise funds to further protect and preserve Australia's national parks. I've been briefed to come up with a logo for this program. Please see attached a mock up of what I'd like to logo to look like. I'd also like to incorporate gumtree leaves in the letter 'H' that the koala sits on. The koala to be used is the same as what's currently on an existing logo. I can supply artwork in digital format for the koala. Below is some additional info for you to get a better understanding of what it is they want. Objectives - To encompass (graphically) their mission – i.e. to protect and preserve Australia’s natural habitat and native animals for future generations. - To incorporate the words ‘Habitat Hero’ within the logo and create a version with the tagline, ‘Protecting and Preserving Parks’. - Create logo variations for use on digital, print, merchandise media - Present 3 logo concepts based on the attached mock up Creative First Draft - Possible direction could be an ‘evolution’ of the their Logo by using the Koala and/or Eucalyptus leaves within a ‘badge’. (see attached) • The Creative Rationale for this direction is as follows  It’s a badge (of honour) – something of which regular givers can be proud.  It’s very Australian  It incorporates the koala from their logo (though we could use a variant of the Koala or even another native animal) – e.g. a kookaburra  It’s simple – white on green or can be reversed out or can be B&W, etc. It can be printed on all printed collateral incl. drink bottles, mouse pads, shirts, caps, phone covers, etc.  The tagline can be removed as required  We could add a sprig of Eucalyptus leaves around the ‘H’ as the ‘H’ represents the gumtree  It’s a circle – representing the unending need for protection and preserving = regular giving
