Animated face

This is used to show the emotion of the robot, this gif took a while to make and you can probably tell it's still a work in progress. It is also. Not that good at all.

3D artist research

MARK VAN HAITSMA

He is a very good 3d modler with my favourite of his works being on Metroid's Samus.

In 2002 he made these images.

On Artstation it says he works in these softwares. 

Mark works as a Bungie senior artist and has made guns for Destiny as shown here. 

I really like his Samus modelling from recently. As this is a Jaeger in the style of Samus.

He also did this image and you can see how much he's developed since 2002. Which is the reason I like his 3d modeling, the development instead of staying at a certain point.
