The Magpies came from behind twice to take a point, a result however that did not stop them from dropping to the bottom of the Premier League.
"Obviously, it wasn’t the result we wanted," said Tindall.
"We wanted to win the game, and set up to win the game.
"I think there were a lot of positives to take from the performance though, especially from an attacking perspective and a physical perspective."
He added: "We asked the group to play with a real intensity and to play on the front foot.
"I think when you look back, the team had 23 shots on goal and nine shots on target, compared to Brentford’s four.
"There were a lot of positives to take, but we’ve obviously conceded three goals and we're disappointed with them.
"We’ll back at those collectively and individually – and we’ll need to put them right on the training ground."
Howe's presence still felt despite him not being there
Today was supposed to be Eddie Howe's first game in charge of Newcastle, but he was struck down with COVID-19 the night before the game.
Despite that, he was still very much involved during today's game, albeit from his hotel room.
Tindall said: "During the game there was a direct link between him and Stephen Purches and he had a live feed so we could communicate with him.
"The substitutions we made, Eddie has to take a lot of the credit for that because Ryan Fraser played a big part in the third goal.”
An 'incredible' atmosphere
Ever since Mike Ashley departed Newcastle, St James' Park has sold out and today was no different.
On the atmosphere in the ground, Tindall said: "It was incredible.
"Every time we have been here as opposition you can only admire it.
"Since we’ve been here we’ve been made to feel welcome and you can see how important the fans are to the team."
Joelinton hailed as 'fantastic' after impressive showing
Supporters have been raving about Joelinton's performance today, and you can see why.
The Brazilian found himself on the scoresheet with a well-taken goal and was comfortably The Toon's best player this afternoon – a showing that was arguably the best we have seen from him in a black and white shirt so far.
Tindall was singing his praises to the press, when he said: "Joelinton's a fantastic player.
Ever since we've been here we've really seen the quality he's got, and the performance he put in today was outstanding."
An anxious wait to see if Howe can make the Arsenal game
Newcastle have a nervous wait on their hands to see if Howe can travel to the Emirates Stadium next week to take charge of his first game.
Although he tested positive yesterday – and will therefore have to self-isolate for 10-days which would rule him out of travelling to Arsenal – he may be able to return in time for next Saturday, if he developed symptoms earlier in the week.
"Hopefully we can have Ed back before the Arsenal game – we’re just waiting on the doctor for that," Tindall said.
"That’s a little bit out of our hands and control.
"Ed will be a big influence on how we prepare."
