Daniel's King Power Play and recommended material

Hello all. I have been playing chess for some years now but never actually studied so no real progress in my game. I only played because I really like to. Now I have started to try and learn a little more and started with Daniel King Power Play series. I think the videos are quite instructive and I have the feeling that my game has improved and I am looking for the patterns and the ideas that are presented in the lessons. What I have is a hard time trying to analyse my own games, but I guess it's a matter of keep trying. I would like if anyone has recommendations about how to approach the game analysis and what do you recommend after I finish with the Power Play lessons.

Thanks in advance!

Thanks! I found at least two. Thank you very much!
