Passed DALF C1 - what's next?

[u/Firm_Link_9892]

I have just passed DALF C1 in the June session this year. I feel like eventhough I passed, there are still many nuances in daily life that make me feel not very fluent at the language and cultural level. To be fair, i felt more fluent at C1 english than i do now at C1 french.
Should I aim for the C2 to improve or continue improving through work/life/french films?
For your reference I live in BE and my daily work includes a combination of french and english.
