I've made some more progress on the head sculpt, there's still quite a bit of cleanup to do and I haven't completely closed the model in yet. The other thing I need to work out is measurements, especially with regards to how it will fit on the transformer. Also looking at it now, I think I need to bring the section of the face with the nose out a bit more. I was also thinking of putting some vents or something in the sides of the helmet, looks too plain with those big holes there.
Hmmm, looking at it now the chin looks a bit pointy too. Might bring it up a bit and round it off more.
Let me know if you have any suggestions for refinement or in regards to my other problem about how you would like it molded to fit on the transformer.
Here's a test render so far:
And I thought I'd play with the colouring, so here is a colour test of the render:
