Any advice for my elf here? Obviously i want to exaggerate some features... but right now i'm feeling a bit clueless 
Loving this thread! Helped alot with creating my Trevelyan

OPTION 1 (lengthening the face)
1. Lower the jaw.
2. Lower the eyes to the new middle.
3. Lower the cheeks to just below the eyes (like you have now, but according to the new eye placement).
4. Bring the eyes together just a touch.
5. Lower the nose to the exact middle point between the brow and the chin.
6. Lower the mouth to 1/3 between nose and chin.
OPTION 2 (retaining face shape)
1. Lower the nose to the exact middle between brown and chin (lower it just a touch).
2. Lower the mouth to 1/3 between nose and chin.
3. Bring the eyes in a touch.
Feel free to post pics of one of both of these options for further comments.
