That is... Great! By far the most lifelike head we've seen so far I think.
I have to agree about the eyes tho, they're slightly off in some way, possibly too crisp in the colouring and the irises are a little large I think.
& the tattoo doesn't look like a tattoo, it looks more like something added onto a photo of a trox (is OmniTec still using photoshop???)
Other than those 2 items, I like it loads!
