Scar tissue after otoplasty, is it normal? (Photo)

Hello, I did otoplasty 1 year ago and one of my ears have a scar that I feel isn’t normal. I think that the scar has been like that since the surgery. But it’s just on of the ears, the other one look and feels much better. When I touch the scar it does not hurt or feel weird it just feels like a thicker scar. Not extremely think but not either straight or plain. What should I do? Is it normal or do I need to fix it? What happens if I not? And what is it and what caused it? I had no typ of infec. The scar sometimes hurts.
