Nice Work MuhammadRadi. I totally get what you are saying. I have worked my entire career as a photographer and now my youngest son is trying to make a go of things with his music. I don't care what genre of art one goes into, it is a struggle, perseverance, dedication and a ton of passion are a must - even then, that does not equal success. Hang in there and keep believing in yourself. I would also recommend contacting a stock agency such as Getting Images or Alamy. Best of luck!
