Well the lioness doesn't look very impressed does she, I expect she was busy and got disturbed, anyway you shouldn't have been watching Leon. Nice capture though.
@kbird61@ladymagpie@joeyc thank you all for your comments. I was just standing there trying to get a good picture of their one year old cubs (didn't get any). The lions have been relocated to this new enclosure a couple of weeks ago, which means no more shooting through glass but the disadvantage of having to shoot from above.
