Do I need fillers & was it a mistake to close my teeth gaps? (Photos)

I am almost complete with Invisalign treatment and I’m panicking thinking I may have made a huge mistake going this route. I had gaps behind both of my top canine teeth. To close them my ortho retracted and tilted my teeth a bit. Since the retraction I’ve felt like I have more wrinkles around my mouth and I look older in general. Also I feel like my tongue is pushed too far back in my throat. I’m wondering if I need fillers or if I do look normal and I’m just paranoid.
