Curious, what do you mean by ‘online degree’? Yes, there are tutorials and various short/comprehensive self-study design courses online, but they are not degrees - you can only get a design degree if you study in a college/university for a minimum of 2 years (associates) or more. Some college/university programs also provide design certificate programs - they’re not degrees, but the next best option for learning professional graphic design. Whether college/university degree/certificate programs are offered in-person or online, there is a huge difference between them and tutorials/self-study courses online.
I concur with everyone here - level up your fundamental design knowledge and skills. I don’t know what you have or haven’t learned of the fundamentals, but, from your work, it appears that you have not learned these essentials.
I’m new to design myself and totally understand the struggle to learn. I started my journey learning design through self-study on Skillshare (definitely recommend Dan Scott!), but at some point, I knew I needed to go further with my design knowledge to gain professional graphic design skills. It would have been best to get an actual degree, but monetary-wise, it wasn’t feasible, so I chose to attend Shillington School of Graphic Design, a design certificate program. But, if you choose something like Shillington, I’d advise to supplement your knowledge and skills with design books and online courses/tutorials cause these certificate programs don’t cover everything.
If you can’t afford any degree or certificate programs right now, then I suggest starting with Baseline, a free online self-study mini-course to get you started with the fundamentals and foundations of graphic design.
I can see your passion for design and you have the potential, so keep learning and growing your knowledge and skills - you can do it!
