Congrats on the launch and all of the work you've done so far!
And major props for working through the critique issue. I was a professional musician right out of college and I was never able to separate the art from the artist and negative critiques/lost auditions really ate at me. The fact that you've recognized and identified the issue and seem to know how to handle it for yourself is huge. A mentor I had in college used to say, "You and your art are strawberry ice cream. You could be the best strawberry ice cream on earth, but when you audition, some people on the other side of the table just like chocolate ice cream. Keep being strawberry ice cream." That is obviously easier said than done. But keep being strawberry ice cream, Bowser. <3
