One problem I have come across with animation is my model dinosaur that I have created has far to many verts. Rendering any animation with this many verts would take days, so I am going back to basics. I am going to learn how to character model properly to get the most out of it when I begin animating, there is a brilliant tutorial found here.

The tutorial goes from scratch to create a life like character, I will work through this tutorial until im confident to begin animating within Blender properly and make something unique to me!
