Beautiful work. I would say that you can't ever get rid of your ego, however you can learn to push it to the side where it no longer takes control of your actions and reactions. We all have moments, especially as teenagers where we let our ego be our guide in how we act towards criticism specially when it is something we are proud of. A sign of growing maturity is to realize that you are the one in control of your ego and learning gracefully to take the good and bad reviews of your work. BTW your first work is not bad. I give props to anyone who has the ability to take what is in the imagination and put it to paper/digital art. I certainly do not have that kind of talent. Hugs and love @positivejolene
