3D Animation (first year of study)

spinosaurus

Not exactly "game art" but our project was to make a trailer for a game thats 1 min or under in under 6 weeks. This is my teams and I's work from our first year of 3D. Any critiques would be appreciated (rigging in particular as its mine and others weak points) due to the gap in skill level between members some parts are lacking in certain areas (lighting in some shots are weird due to light links etc) any thing that would help us improve is great
