Your Opinion - True vs. Aesthetic Centering?

I just finished sewing a simple design of a horse silhouette on a vest back. I centered the center (that sounds funny, sorry) of the design with a tag on the back of the vest. Although I know that is the true center, to me, it just looks a little bit off due to the shape of the horse. My question to you pros is, would you have done what I did and used the true center, or would you have eyeballed it and centered it where it "looked" centered with respect to the tag?

Thank you, Robert. That was kind of my thinking, but it is good to hear confirmation from an expert.

After all that hemming and hawing, I accidently sprayed the silly vest with 505 instead of Magic Sizing...now it has two little adhesive stains that I can't seem to get out...I've tried Spray N Wash and Goo Gone to no avail yet...

With my luck, I will probably have to end up buying her a new vest, and then I can make sure the logo is visually centered....Haha.
