Great job with the CAD work. I can critique the design a bit:

You're going to have all kinds of trouble with the sliding link. A good rule of thumb for sliding joints is that the ratio between bearing length (in the direction of sliding), and bearing diameter (or spacing) should be greater than 2:1, otherwise when one side starts to grip a bit, the whole bearing will twist and jam. You've got hardly any bearing length in this sketch, so jamming would be a real concern.

Another good rule of thumb is to prefer rotating joints to sliding joints - so if you can redesign this to use a trailing arm, you'll have more chance of success.
