camera parameters

Hi all, I have the following question, to rotate my character on the X axis, in my view top visualize well, but has a slight tilt camera, even though distanced the camera, this continues with its depth, there is a form of move some parameter to change the camera?

if I place the camera in the center of the character is displayed fine, but if I move the character to the sides, is the slight tilt to one side.

any suggestions
thank you very much for your time

I guess this is just a matter of perspective. When you look at a tilted object from the side, it appears skewed.

If you just want to squash the character, then you could squash it by scaling it instead of tilting it.
