You have too many good reviews/client feedback to "suck," so you can rule that out. But I would suggest asking every client to leave feedback at the end of a job. They won't always do it, but nothing says, "He's/She's really good" better than glowing feedback. You have quite a few completed jobs where the client didn't leave any.
Are your prices too high? Who knows? Your earnings are hidden, with only your hourly rate visible. I've seen cases where they differ drastically. Potential clients might presume you're out of their league (although maybe not...my rate and earnings are visible and I get invitations all the time to work for ridiculously low fees). But about half of the jobs I do accept come from invitations to apply from clients who've seen my profile.
There's plenty of work available, although some of it doesn't pay well. I've seen a lot of "I'm just starting out..." in ads lately as an excuse for offering to pay less than what you'd make bagging groceries. (In the last 30 days I've gotten something like two dozen invitations to interview for ghostwriting, which I turn down because of unrealistic terms (15k a week, have to provide my own storyline, 1 or 2 cents per word, unlimited revisions). My own experience on Upwork (7 years) is that of a steady upward trajectory, sometimes balancing four or five active jobs in a given week. I stay very busy, both with private clients and through Upwork...and I don't participate in the "race to the bottom" that so many indulge in. This income supplements my retirement.
The key might be in landing regular clients who can be counted on for a few hours of work every week. Might be hard to get, but keep trying, and good luck to you.
