I believe you, actually, the time and effort we've put into the translation outweigh the benefits we've gained. And, as you said, the design of the bilingual subtitles is flawed, making them appear bulky and unattractive. The language-switching is also meaningless, which makes me question whether it's worth it during development. It likely would have been rejected early on if this were a commercial project. Pointing out those problems shows that you have excellent project management skills. These skills will undoubtedly help you succeed in your future career.
Though, I believe that people who understand both languages would enjoy it.
