Question 1 (Duck): It is good that more than one sketches are drawn. But however, there should be a sketch for the overall of the mechanism from the front/side view. Only from the bottom view of the whole mechanism, I cannot really tell how it will look like (I cannot even tell there is a duck there). Question 2 (Table): Even though the second sketch was clear with all the labels and have more than one sketch to show when it is locked and unlocked, it lacks the application part. The table was not drawn out, so I would not know where the linkages are going to be placed at.
