What are the chances of getting a DTV visa after studying Thai in Bangkok and freelancing as a designer?

I’m currently in Hanoi preparing to apply for the DTV visa, but after reading a lot of recent experiences, I’m starting to feel a bit unsure. Last year, I entered Thailand on a 60-day tourist visa and later enrolled in a six-month Thai language course. With the proper visa extensions, I was able to stay for a full year—all completely by the book. I’ve never done any border runs or overstayed. I even took a short solo trip to Hong Kong to visit art exhibitions with friends during that time.

I’m now applying for the DTV as a freelance graphic designer, and I have all the required documentation ready—proof of income, an extensive portfolio, and everything else listed in the guidelines. At first, I thought my clean history and the fact that I followed all the rules would work in my favor. But some of the posts I’ve come across suggest otherwise, and now I’m wondering: could studying Thai in Bangkok actually hurt my chances instead of helping them?
