Legality of doing art commission while being employed

Hello everyone

I believe someone had already posted a similar post mine, but I wanted to make sure if my situation would apply similarly to them.

So I work as a translator full time on a work visa, specifically the Engineer/Specialist in Humanities/International Service. I'm thinking of doing some side jobs by taking art commissions and such.

I'm wondering if taking art commissions still fall part of my visa category. Since the company I'm working for generally does not allow side jobs, I can't really make a submission to work outside of my work application to the immigration office.

I'm also planning to try and apply for PR in future. I've already been in here for 8 years , and I'm wondering if doing art commission would affect my PR application due to not applying for 資格外活動許可

Any suggestions would be appreciated.
