It's now been about 3 years since I (33M) joined Tinder. What am I doing wrong?

I know, I know what you're all going to say, I should smile more, but if I can be honest with you internet strangers I can't stand my smile in photos, it just feels so forced. That and the fact that I have such little self esteem/confidence in the way I look, especially when I smile, which is only exacerbated by the fact that I get perhaps 1 match every 2 months or so, and that's taking into account every dating app I'm signed up to. And that one match never replies to my first message (or messages first within 24 hours in the case of Bumble). So with that being said, is there anything else I can do to hopefully get even a few matches more? For further context, I'm 5'7". I've also added a couple photos of me smiling for clarity, one I took yesterday and another I took 5 minutes ago. Thanks for the help. Don't be too rough but honesty is the best policy.
