They are zoo shots. I've got a rule about zoo shots, 'you're taking pictures of animals trapped in cages. They better be bloody perfect or they're a waste of time'. I feel quite strongly about it, and typically phrase it more colourfully
but didn't want to put you off.
So number 1 is fantastic (although a little soft on the hindquarters) and 7 is alright, as is 8. The rest are not.
2 is unbalanced and faded.
3 is OOF
4 is soft and the composition isn't great
5 & 6 are behind bars
8 is missing a nose
Don't want to be too much of a wet shower, but if you're going to take a picture in a zoo, you typically have to wait about 60 seconds for a half way decent shot to come along. If you can't be arsed to wait 60 seconds, then that's just downright lazy. If the animal in question isn't sitting perfectly, or won't lift it's head for a better pic, then move to the next enclosure, where I guarantee you there will be another photogenic animal.
