I'm not an expert in this stuff, but your leg kicks seemed good and yourstepping jab was nice. 1) Props for stepping in the cage 2) it looked like the guy had no real standup, so why not go with your stand up game he was backing up. I wouldn't second guess yourself too much, looked like he got lucky with a couple of overhands. It looked like the desperation throws of someone who ate of couple of good shots and didn't want any more.
Good luck in the future.
