Draw possible for black or lost?

http://en.lichess.org/ZJBIy8P0/black

Performed fairly well in this game( i'm around 1225 player) at move 57 I felt that I might be able to pull out a draw as black, was this a possibility? or was I dreaming lol...what would be continuation for black?

appreciate any tips, comments and your time

Edit: blundered my rook and lost in end -_-

''Draw possible for black or lost?''
Lost.

Just to provide a more constructive post, you can tell that its completely lost at move 64 (before you blunder your rook) since your king is stuck in the first rank, which really only leaves you with a rook vs king and pawn and bishop and rook, so no matter what kind of exchanges happen, white will always have enough mating material.

ok, understood,appreciate your input. Thought so just had an instinct . a misguided one it seems

Thanks again and happy hunting
