really good shots. even though you didn't get close enough i bet you were using a pretty good camera..... some shots have really nice focus.
all the animals that are born in wild are afraid of humans. the trick you can do is stay very still or move forward very slowly. sudden movement will scare them away. if you just sit like a stone they might think of you as a stone and won't be afraid and you can take close shots.....
but this will be extremely hard
