There are going to be people who are not going to like your art, are not going to understand your art, and are not going to care about your art.
Pay no attention. It could be a matter of taste, opinion, jealousy, or dislike for no reason. As long as you are doing what your heart desires, you are not hurting anybody’s free will, and you are happy, keep moving forward. You cannot please everyone, and you should never try.
Keep pushing, there is no time limit and you will get better.
Shine On and Create.
