Hello! I really love it. I practice Jazz Piano on Open Studio and my playing really starts to sound good thanks to you guys. And it makes so much fun. I have 3 recommendations: 1) I didn't like that during the look and feel change of the Open Studio website all of my progress in my current course was erased. I had to mark every lesson as completed again. Please consider this in future updates. 2) Some of the courses lead to a dead link. For example "Jazz Piano Fundamentals" and "Jazz Piano Transcriptions | Vol. 1". You may want to fix this. 3) Could you make a more theory heavy course? I just started with the Jazz Chords course and it works for me. Adam always mentiones that we don't need to unterstand the theory to play these chords. But actually, it would help me to unterstand some of the motivations behind the voice leading. If there is a theory course in the higher levels and i haven't found it yet, please forget my suggestion please. You are doing a great. I love your work and passion. Hava a nice day, David Enajat
