I think its a great shot!
On the one hand you need to be SO lucky to meet one... not just in the zoo, but out in the wild!!!
They are so shy and seldom and during the day they would know how to hide from our eyes...
Thus on the other hand, im sure many of us were already closer do one of them as we might think.
But we just could not see them hidden in the trees and branches because they are so well camouflaged.
I spend a lot of time running in the forest or so, but i never saw one in all the years...
This one is really HUGE and looking straight into the camera!!!
Its a beautiful one and very impressing indeed.
Im really jealous, but you deserved the shot by paying attention for the surrounding.
And of course, because of the good reaction and having the camera with you on that day.
Naturally a little luck is needed for something like this, but if one uses the watchful eyes
to see and pays attention to ones environment one can find such opportunities.
Most of them are nocturnal...
At night or during evening its so hard to get a good picture especially behind all the leafage.
And on top, i doubt many of us would spend most of their nights somewhere in the forest.
Thats why im fine with the light settings, the wonderful motive makes up for that by far
Congratulations on it, well done!
