side track exercise

So there I was,
ready with the drawings of the gargouilles... all proyected and ready to show to the French clients, ...
and no space to make that big sculpture.
Then I thought of that other proyect still lingering in my head:
making busts!
I have had some classes lightyears ago from David Smithson back in the days of the Fine art school in Den Bosch (Akademie voor vormgeving en kunst ´s-Hertogenbosch, graduated 1999) and I enjoy modelling faces, or heads.
Usually I don´t have a model to follow and any given outcome, if credible is o.k.
So I wanted the challenge higer: Making the bust of my boss' 2 children. Well, 1 baby, just over a year and the older is now ... about 4 years old.
On the photo day one. Not much happening.
I've shot over a 100 photos of the kids trying to get all angles.. didn't get all as I wanted,
but hey! Am I an artist or what??????
Anyways... I fear a lot of work need to be done still, I suspect some terrible wrong porporcions here....
Comments, anyone????
