There is plenty of space for improvement like others have said here and i think it just needs a bit more time.

llms are great at languages but you dont just ask it to "translate from english to other supported languagues" it generates things that are hard to understand. when we talk about translation in real world we're actually talking about is a fundamental re-intepretation(transcreation) of the source text through target language's local, native mindset, and you should do the same with llms.
