All good shots Loz
Chimp looks well bored ! hehehe
The otter shot, if the depth of field had been a little longer, or shorter, to get the background otter either in focus or very out of it, would have been much better (in my opinion of course)
The Zebras is for me the best of the 3, as Ken says, the repetititititititititiveness (hoiw many t's you need in there Ken
)
