Well, for the top one, the skull looks totally different than it does in the sideview. The lumps on the sides are gone, the forehead-nose area looks narrower, and I don't even know what's going on with the eyeholes. I think the nostrils are too visible as well. The arm looks a little weird, maybe make the paw just a bit bigger? Same goes for the shoulder, perhaps widen where it attaches by just a bit. The closer leg looks weird when it's in the back position, I think it's too dark, especially when compared to the leg in the other two, where it's much lighter. I think that's all I've got for now.
thanks
How do these updates look? (newest=last)
oh, and when a marowak has it's eyes open, you can just see the white part, which is why they look so different
and it's supposed to have a 0_0 expression ... 0-0... O.O....
