My first brilliant... followed by my 2nd

Hi guys! 

Today I played in a blitz arena and played a 1350 in a game. This was quite unfair - I was nearing 1200 but I managed to win (even though I didn't even realise I did the brilliants ).

Here's the game:

I did the brilliant(s) on move 26 and 27. 

So, what do you think? 

Why were these brilliants?

Feel free to post the answers in the comments or PM them to me.

PS I know the answers.

See you later!
