I would just do an image search for that character. This looks like one of his common poses that you can practice. Make sure your shoulders are at an angle towards the camera, put a little more weight on the back foot and turn your head towards the camera. Practice until you are happy.
The second pose is basically the same except your arms are down instead of crossed.
