The UV should be fixed, it is calling for an update. Some of the animations need some work, for Stand - 2 make sure they move their heads different directions and at different times. For Death you need to make it happen slower. Perhaps slowly fall down on to his side then in his final breathes, lift up his head and make a loud screech.
The area where his skull should be should be more visible, right now it looks like he has a never ending neck. The arms should be much thinner compaired to the massive legs it should have, and the claws/nails don't look great. They look pryed upwards and he only has one on each leg / arm. You desperatley need to give him a new saddle and when the skin, which is being made, is done you can use that for it. Also, his tail needs to be longer, it looks small and baby-like. He is a manly raptor!
Also, from what I can see.. The troll on the left is an Ice Troll and the Troll on the right is a Forest Troll. I do not see any Jungle Trolls.
Overall pretty nice. I would agree with Donut, 3/5.. The animations need some touch ups and the mesh just needs some finalizing. I love your model but there is still a bit of room for improvement.
A final little note I wish to leave: "I am only trying to give you the best critisism possible, not make everyone hate it. We all know you are very skilled and we want to keep it that way."
