New here + Should I delete my existing profiles? + Rate my photos

Hello all, I'm Gib, 36, living in Hollywood, just signed up for the course this morning and I'm already learning.

Quick question - Should I delete my existing profiles on various apps and make new ones? I've had some of them for years and gone through long periods without using them (not actively suspended, I just wasn't logging in) so maybe they've been pushed to the bottom even though I've started using them again? It's extremely rare for me to get any matches, especially on Bumble.

If I do delete them and start new profiles, does it need to be under a new phone number?

I'd also be down for some vicious feedback on my photos. Some are from the same day, I'm not sure which ones best.
