Overall Feedback: The only way to improve one's ability in any language is to actively immerse oneself in it. My advice will always be the same: keep reading English books and magazines and newspaper articles, keep watching English movies, series, and documentaries, listen to English radio, and, most importantly, speak as much English to yourself and others as possible. The key to excelling in any language is to learn how to think in the language you are learning. Make this your priority.
