Some comments on the beginning.
Your top right stones are low, so playing on the top is not urgent. White left weakness in the top right, and you want to expand your kobayashi framework, so a play on the right is better.
This is a bad shape. Either keima into the corner, or make a move like this. Doing both leaves bad aji.
This makes him stronger in the area. 
Good. 
This is terrible. If white just ataris you down, you can connect underneath, but you lose a ton in the lower right corner. The best way to attack is to seal them in. They probably won't die, but they'll live small while you build strength.
