How can I improve my speaking skills ?

The most important thing to improve your speaking skills, is to be confident when you speak in the other language (with me French). That is the main thing I will focus on. After you feel confident, you will improve easily by speaking as much as you can and listening to anything you can find. Then I would suggest finding some interesting words such as 'cependant' or 'de plus' and learn how to make good use of it.
