Low Poly T-Rex

This is my first animal Blender project and basically only my 10th blender project in total. I am very new to Blender and mostly do it as a hobby and am doing this for a school project. It should be 3D printable as I am 3D printing this myself as well, however print this at you're own risk as I am not 100% sure if it works and may need to be printed in 2 parts. As this is one of my first projects any feedback is appreciated.
