Elephant sketch and draft

A customer asked if I could do a picture of elephants. Not one to shirk a challenge I thought I’d give it a go. Being a fan of David Shepherd I felt inspired to create something characterful.
 
Below is the initial sketch and the worked up draft. The elephants are drawn freehand from a number of reference photographs and drawings.
 
I’m still trying to get the infant to look less like a cartoon rendition.

I will post further updates on how I get on with this project, in due course
