>>34951084...and? I'm seeing the same exact problems. Its arms are so short and tiny it constantly looks as if it's reaching for a hug. In the sprites, the arms clearly reach to the legs -- the model's arms may reach that far, but it'd be a struggle.
Another problem is the legs are also short -- in the sprites, the top of the legs come up to the line across the belly, they clearly don't hit that high in the model. Which, I suppose, could mean the shell itself is too large, considering the extremities all appear to be too small in comparison.
