Finally installed EFM and was able to keep the sculpt as it was. Finally able to move the bottom teeth around thanks to EFM so he actually looks like he's growling/snarling now. Also tried Maximum Carnage and Dirt and Blood - Dynamic Effects. Seems better than Bloody Facials (hue) and it actually looks like blood. Not sure about Carnage tho, the gore effects barely pop up.

So hopefully better facial expressions and eye movement from now on.
