Put me in the "would love to see a mask" column. -- But only because the alternative I'd suggest, "softening up the facial features", is likely near-impossible to do. I think she looks great so far, and if you hadn't listed it as a WIP, I would have assumed she was finished.
I guess I'm a dirty sexist pig, but I always pictured female preds as a tad smaller than the males (unlike the Aliens, who have a hive/queen structure) - but I like that this one is as big as her brothers. And having one of your creations in my collection, I know exactly how big she is.
Great work guys! Looking forward to the finished "preduct"
