Congratulations
Myself went out and got a few hours under my belt stretching further afield as my confidence had built up. One year later after my PPL I did an IMC, I recomend the IMC as it builds confidence in more complex proceedures and radio work, as well as allowing you to get out off sticky situations when the weather goes abit pear shaped. After the course I promise you, you will have so much more confidence in your flying, and also it can get very prity above the clouds or between layers.
good luck
