Draw vs. a 1900 otb (unrated, endgame)

The last few moves of the game just show how I managed to draw, I was a whole piece up at one point then he won it back, shame the whole game wasn't notated it was a classic but I remember the last few moves from the game...

This is how the game finished and the draw was agreed  I have some hope of destroying my ~1600-1700 rated opponent on Saturday!
