Don't worry, you can still make Oblivion like faces.

PS. I wonder if someone can guess who I was sketching in first pic but it is unlikely, I wasn't that good. The second pic is actually a random image from web, I don't know why but it looks like Oblivion faces.
PPS. I know 2D is different from 3D but I am just giving an example.
