Nile Crocodile sculpt- work in progress

This piece is not finished yet but I thought I'd post up a picture at this stage to show where I'm at with it.
I've still got the base to create and before that I have to finishe up some details on the underside of the tail.
Sculpted in Sculpey Firm over an aluminium tubing armature. It measures approximately 20" from head to tail.
