They do look rather menacing. I can see why you were glad they were fenced. If you have Photoshop though, you could get rid of that fence in 2 or 3 minutes. Very easy to do with the content aware healing tool. Then you could pretend you were fearlessly staring down a pack of wild beasts.
I think the fence gives us a sense of their potential danger (as do those amazing horns!). And yes, those staring faces! Glad you were on the other side, Diana! :)
