Bumrah has become a lot more aggressive than before on the field

This isn't a criticism. He is becoming fierce and scary even for the Australians, dominating them like Kohli used to at one time. Just an observation on how Bumrah engages and celebrates a lot more than he used to do until 2-3 years before. He is giving death stares, celebrating aggressively and engaging with them. He has also beefed up a lot more, if we compare his physique 2-3 years ago. He is in his prime and this I think it suits him as a Fast Bowler. There are very few such aggressive bowlers like him right now in Cricket. An aggressive fast bowling 'Captain' who dominates the batsmen - Never thought would see this day! Now, need one equally good hunting partner with him. Siraj could've have been but he isn't in his best form.
