I got a reply to the email I sent to Nick Roberson today:
Hi Alistair,
What a great start!!! I love the sculpts. I would say thet the male has eyes that are set more into the head slightly by the look of it and this works well. The girls are rather 'stuck on' ( possibly something to do with the cheeks) but with all the other stuff to do this is very minor.
The hair for me is fab, its flat style is great and you could certainly push this further next time into more of a defining style.
Looking at these images, I am very keen to see the bodies and the animation of course!!
As for painting, you may want to shade the heads, (that is what I would do) but again its time that is the biggest enemy as you know.
Keep me posted.
As for me i am due to visit NEWI soon for a 2 day sculpting course which i am now doing at 11 unis around the country. Staffs have a very good stopmotion only course ( the only in the country) and may have an an M.A. if you are thinking about studying further.
Anyway, hope to catch up soon.
Regards Nick.
Some encouraging words.
