Yes you do. There is still more to learn than any one person can, even in a lifetime. Many people can draw technically very well; it's an important beginning. Few people get it so well so young. I did and it seems as you have too. Where the journey goes next is up to you. A good start is to open up to all the amazing work that's come before you. I'm sure you've already started. Check my journal post on Blogs and you will find some inspiration from the great master illustrators both past and present. If such work can be done, then those who aspire may accomplish it as well. Good luck and keep in touch when you can.
