I saw this a while on cg society and wanted to comment. This is a perfect example how the image references aren’t enough when making a portrait. You don’t ever have a real side photo or front for that matter, it’s always but for a milimeter at least to one side or the other, so you can’t ever grasp the pproportions and relations. I was all hiped up about image plane zpluging, and now I never use it. Instead, I get a LOT of reference, movies, photos ets., and observe them whil sculpting, not even the base mesh over a reference. Hope this helps, good work though overall ;)

Very nice expressions! Love the feeling, kind of right inbetween realistic and exaggerated! How did you create the hair? Is it Maya hair?

cherub_rock: Thanks for the crits and comments. I agree with what you say. Its really tough to get the ref you need from any arb pics off the net. Though I still find the imageplane really useful. Its also my 1st time using it. I wanted to try a different method this time round. I ended up screen capping a lot from transformers. My biggest problem was relating an expression with an emotion. on a still image an expression can read many things. But in live footage or animation the emotion comes accross clearer.
Gaarder: hehe. Thanks man. The hair was created using shave and a haircut and rendered as hairprims in mental ray. Nothing fancy.
fantastic work indeed!
