Life In 19x19

Greetings all, I am a beginner to Go and have been playing primarily MFOG against computer of 18k (it's free version, can't change strength of AI). I have a game that I lost by 29.5 points (computer was white with 6.5 komi) on a 13x13 board. I'd like opinions and discussion, if possible. File is an attachment. Thanks.

Quote my post to see how to put up games like this.

Thanks, here it is:

For 20k, you are pretty good, especially in opening.

Here are a few small comments...
