Yes, they look off center, but that's cause I didn't move the camera at all while taking the pictures or resize them so that you could get a good idea of the size difference, 1 is about 8 ft tall in world, and 10 is about 12 ft tall. Though my fursona could change over all size to macro too, I'm just not good at scaling that kind of stuff on SL. 1 and 2 look similar because 2 is a mesh body from L'uomo, it's difficult to tell, but it has more definition and a bit slimmer in areas.
