11... Ne5??, allowing for gxf6! is not best, better is 11.... Nh7.

14...b5?? amused me greatly that you sought to lash out immediately without taking stock of your situation. 

19. Rd8?? Wretched on my part, overlooked (after Qf4+) Raxc7, where black still has hope. Much better was Rd6!

26. Bf2+?? A strong move, but not nearly, nearly as good as Rxc8+ with an almost instant win.

29. Rd8?? An absolutely, completely wretched move. Just about any other intelligent move held the advantage. This allows black to equalize.

And of course 33. Rh8 might not be the best move :P.
