Scarey eyes! Use the same projection method to do the eyes. If you still have the project you used for the front of the face in the scene apply it to the eyes.
Also, see these for reference for your character design:http://p2.la-img.com/1184/25078/9208322_1_m.jpghttp://p2.la-img.com/1348/27828/10590217_1_m.jpghttp://p2.la-img.com/46/23567/8370656_1_l.jpghttp://p2.la-img.com/921/26838/10101838_1_l.jpghttp://www.eliteauction.com/catalogues/060411/images/408_1.jpghttp://www.burchardgalleries.com/auctions/2003/feb1603/l006.jpgI realise these are from a different part of the world but the staging and execution of these designs are my main focal point.
One final suggestion. It occurs to me that you need to put nature at the heart of your design and create interesting silhouettes. Your design is 'of the earth' and therefore needs natural materials at its core. It could be anything from drift wood to seaweed that inspires the structure.
