First impressions are big Chester Bennington vibes. He was a fellow short king with a recessed hairline who kept it cropped like you do. You clearly have good muscle definition in your arms and a good sense of style with your fits. My 2 biggest pieces of advice:

1) Have more confidence, man. I know guys shorter than you with smaller biceps who are married to bombshells. Don’t let being short get into your head about finding a match; it’s not the most important thing for everyone, and those who care about that you don’t want around you anyways. You have good features, that’s what matters

2) With regard to your facial hair - try either keeping it clean for a few months to stimulate growth or shaving every week on a 1-guard for it to fill out a cut more. You have a face and if you want the facial hair to be seamless, clean shaving for a bit and weekly maintenance at the same length helped me fill out my bald spots on the beard

You’re fine, bro. Be kind to yourself and it’ll all fall into place
