Now I have been looking for a good lizard – sounds like a personal problem I know, but it is hard to get something with the right morphology (proportion and placement of body parts):

This model comes close – a torturous thing in parts that comes together with the most lovely legs (toes and all) and a sculpty tail – not sure about the head though, there is plenty of paper but a goanna typically has a much longer neck (although this model does have the beginnings of a lovely forked tongue also)

An interesting use of a hexaonal base and some lovely sinks and collapses – I could see this base as a useful starting point for a crocodile, as there is plenty of paper doen the back to crimp up some lovely bumpy bits. I think there were some inaccuracies in the diagramming, as the initial folding of the toes, according to diagrammed landmarks was less successful, but minor adjustments sort that out.

When I fold this again I think the resultant critter will be much better shaped, now I know what is going to end up where – still, an interesting fold.
