Hmmm... For Directly Above, try googling image for "Bunny Back" or "Rabbit Back" or some variation, I bet you'll get just what you're after.
And to have images at the same scale, just resize the different images to the size of the smallest one, simple
The only thing you have to worry about is the different body orientations of the rabbit, such as turned head, or no turned head.
Jess.
[EDIT]
I just looked over the ones I'd uploaded for you, and there is a directly down one in there for you ( you can't see the tail, but it's close enough )
