Help with my model.

I’m modeling a Jaguar animal. How do I model the eyes?
Look at the front view. The left line of vertices isn’t aligned right, the end shouldn’t be touching the nose, I want it to be aligned exactly like the right line, how do I do this?

Simply, I want both eye loops to be alligned with the Jaguar’s eyes.
Why did my reference photos dissapear all the sudden!?
Sorry, I’m new to blender.
Should I use images that are perfectly aligned, where the front or side is aligned perfectly with my view? will they make my modeling faster and easier? or is any image fine? what do you guys suggest?

There are no images packed in the file.
