Interlink Head Study--sketch

Just posting this for   I've commissioned two more plushies from her of Triage and Interlink.  I'd only ever drawn Interlink from the front, so here are a few head studies to help her along. 

The circular cooling vent that takes up most of the back of his helm is not visible unless you remove his back-plate.  Even if he turns his head, his large shoulder-caps would still obscure the feature. 

As with all of the other sketches I've posted, this will get ink and color sometime in the indeterminate future.

It's really fun drawing Transformer characters that turn into something other than a car or plane.
