Hi.
Submissions 65 and 66 show promise. How about considering these 2 ideas:
-raise the right limb of the "V" in veterinary to straight up an down, include the "V" as the same color as the falling dominos and have the dog's paw just touching the right limb of the "V" to set the dominos falling to the left.
-also have the cat figure be a semi-crouched down cat sneaking across the top of the dominos with the "D" in a larger size. (bump caps)
