How could I have gotten more profit from this attack? Review request 12 vs 12

I felt like I was in a good position and had a week group to attack, but I feel like I should have got more profit from it.

I’m not a DAN player but I make a review for you with things that I think that can improve.

About the group, I think that you attacked thinking in kill them, but It’ was in fuseki of the game, It was very early to try kill him, you needed more support stones, the board was open yet, you should make other big moves.

I make some variations about all the game, with others attacks that makes territory profit to you.
