As a long time two hander; that is not bad at all for just starting out. The one thing I would change is to stand a little taller throughout your approach to take strain off your lower back. When you bend at your waist and get "top heavy", that can create some issues with your back more over the long term than the short term. I have been doing this since 1992 and still doing it full time to this day. Here is my video to give you an idea what I am talking about.
