I'm not sure what you're going for... do you want to expand on doing event photography or get into doing portraits? If that, what? seniors, families, engagements?
You need a professional website that you can direct back to from your social media. You need a solid portfolio; I quit looking after awhile. And certainly for pro work, no cats, no cars, or what you ate for dinner! lol Keep that stuff for your personal social media, just for fun, but - keep in mind that if anyone looks at any of your photos there's probably going to be an expectation that even casual fun pictures will be good/pro quality.
I am not sure from your Instagram if you aren't always nailing the exposures and have done a lot of editing to try and fix it, or if what I'm seeing is from instagramming the heck out of them. Go thru and edit that waaaaaay down for a professional portfolio. Pick your best. There's some good stuff in there, particularly some of the close up or what I think of as in-game (or in this case, event) portraits. But I don't see any photos that show me you do portraits, and I see quite a few that aren't sharp or could have been framed better. Do some editing down from all those photos and use the best - if there's one you like or is a great memory but isn't the greatest image, keep it for your personal collection.
Doing events (or anything really) I learned to go for a 'clean' composition, meaning to minimize visual clutter; if something isn't adding to the photo, keep it out of the frame. Think about vantage point; work thru the crowd, lean, whatever it takes to get a better photo framed. Make sure the camera's straight. It probably wouldn't hurt to keep learning and practicing and keep working toward bringing up your skill level. I've been a photographer forever and still can get rusty and need practice.
You may eventually need a portfolio with separate sections for events/music and portraits. I don't know how you can expect to get wedding clients when I see nothing wedding. It seems like social media seems to attract people who just want cheap. Sounds like you wasted time waiting to discuss price so that's where it would help to learn marketing and how to present yourself. Probably prospective clients who want a good wedding photographer are going to go find one and be prepared to pay the going rate and I don't think you'll find them posting concert photos on social media.
I was wondering with the music photos if that could relate more to senior portraits, or maybe engagements? I dunno... If you aren't already, start learning about releases because even though a concert was attended by the public you can't use photos of the band for commercial purposes without signed releases. Get on
American Society of Media Photographers - Homepage or PPA and start learning about releases, contracts, etc. etc. John's right about the business aspect of it, and ASMP does webinars (free, just sign up and they email you a link).
I would say I see potential there, and you've got your work cut out for you. I don't think anybody's making a lot of money at photography (or ever did, really), and anybody I know locally does it part time/seasonally (sports) so you gotta love it and probably figure out how it could work along with another job/other work and build from there.
