Is This A New Variation?

I just played a game featuring the Taimanov Sicilian, an opening I have never played with or against. I was white, and my opponent chose a less popular line:

at this point, I did not know what to do, as I had not studied this opening before. I thought I came up with a novelty when I played these moves, which only appeared 10-20 times in the entire database.

as you can see, the opening moves are the same, but I played a strange continuation, which I am not sure if the engine favors. good bye for now.
