There is nothing wrong with acknowledging any benefits of sobriety, and nothing to be ashamed of about wanting to look good (or better). Who does not? There have been many threads about the positive effects of sobriety on our appearance here, it seems like a quite general experience.
I understand insecurities and issues related to the perception of our physical appearance, had lots myself when I was a kid. I also habitually avoided looking in the mirror during my worst drinking times and felt quite like you in early sobriety that finally I could open my (no longer bloodshot) eyes.
Whether it's improved appearance or increased confidence, both of these are good things and I'm sure both of them are also true. Congrats!
