Balcides, your beast looks incredable. I didn’t see anything wrong with the eyes. If you want to make it easier for the viewer to see where the eyes are you could always model a set of blinders on the sides of its head where its eyes are. Then they would sort of make the viewer look where the eyes are.
One question: What is that big thing behind the beast going to be. I can see that the beast is pulling it, but I couldn’t tell what it was.
Great work on everything so far. That harness is absolutely awesome.
