Is my sourdough dead ?

 hi, I created a sourdough starter for the first time on 1 October 2020.

I have been feeding it 30g water and 30g flour. I started using farina00 flour as I did not have rye or bread flour at the time. I have been feeding it everyday and on day 3 I fed it twice. It smelt a bit like cheese during days 2-3 however after feeding twice a day the cheese smell has gone away. Everyday I see some bubbling however it has not risen. 

Today on the 5 the day I decided to change my flour when feeding as I thought it might be the reason my starter was not rising. I fed it 30g original starter 15g bread flour, 15g rye flour and 30g water. I have seen some bubbles form has it smells quite pleasant however still no rise.

Am I doing something wrong should my starter have begun rising by now have I killed it?

please help thank you
