Minor Project - Garbage-o-saur Reworked

For the design of the Garbage-o-saur I have been looking at the classic, generic American trash can for the basic shapes of the character. Since the animation is set in America I feel as if this makes most sense as it would not fit the environment having a wheelie bin shape for example. I have been working on the design and come down to two rough designs. The main difference between the characters is the characters arms. I wanted the Garbage-o-saur to have small arms as obviously trash cans do not have arms, so this suits better rather then having giant strong arms attached to it. In the two designs I have just a normal straight arm and then a curved chicken wing shape arm. I feel as if the chicken wing shape works the best for the character as it is suited for a dinosaur and the arms aren't overly practical so it fits into the criteria I would like for the character. I also feel as if having the chicken wing arm will allow for easier animation as I would be able to use and IK handle for the movements of the arm.
