Just watch deer!

The only time I really see deer peal their ears straight back is when they take off, or are ducking down to move through stuff - so i always try to have some sort of directional to them. In reality though - you're never wrong. As long as the base-butts are in the right position to the skull, you can litterally just about point the ears in any direction and not be "wrong" as long as its physically possible and probable.

Here is the one my taxi is doing for me right now. He started off with the right side a little further back, and I moved it forward jsut a touch so that it would be "listening where it was looking" - My taxi is awesome though, and I barely touched them...

I took this picture when I went in to position the ears on Christmas eve. I should be picking it up within the next week.
