I was wondering if my gigs needed any improvements or suggestions.
You still have room for one more gig. Maybe try to make something along the lines of your Astronomy and Space Science degree from South Dakota School of Mines and Technology?
Seriously, though, integrity is important in business. You should remove the ‘do anything’ gig, as recommended in your other thread.
You only have 34 minutes of read-time shown in your forum profile. Check out the Tips For Sellers category (forum.fiverr.com/c/Fiverr-Tips/tips-for-sellers/l/top/all?order=views). You’ll find hundreds of threads offering advice on a variety of things to consider and/or improve. (Note: Not all advice can apply to all gigs or categories. Be sure you check multiple sources as there are some false tips, even among the top threads.)
It takes a lot of work to make it as a freelancer, so be sure to research and plan accordingly.
