Pawn for A Rook?

This game was pretty interesting, I had to sacrifice a rook but by the end result meant death to my opponent.  Nice way to start off the year.  At the moment I play very risky and part of that is due to my lack of experience playing chess.  The other part is that I am very aggressive on the chess board.  I'm learning what works and what does not work, if you see anything I missed let me know.
