Passed Azure 900- What Next?

I have a few ideas of what I would like to do next. I have been looking at Az 104 learn the admin side of Azure more. I would eventually like do to Azure 305 so I can become a Cloud Architect.

Any other suggestions?

Edit: Thank you all for the advice.

For the people that asked:

I used the John Savills videos and learn azure in a weekend by 28 minutes on udemy, they helped a lot. There were some questions about storage, which weren't my strongest area. Asking about hot , cold and Archived storage. It was quite a Broad range of questions to give an example I'm afraid. I do work with Azure daily so this helped me, but mostly with groups, users and permissions. I also used a website called measure up for mock exams and a website called skillcert Pro.
