If you want to be an artist, you are already halfway there! There are so many different ways for you to be an artist so don't be discouraged if it takes you a while to figure out what your best at and what you enjoy. For instance, you can work with pencils, paints, markers, photography, clay or so many other types of materials. Never get discouraged if something doesn't quite work out the way you'd like because sometimes it takes artists days, months or even years to finish their works of arts! Art is a way to express yourself so don't feel like you need to follow someone's else's style. You will certainly find artists who will inspire you; however, bring your own style to your work. Remember, there is only one you in this world and only you can see things they way you want to express them!
I can't remember my first picture but I do remember always drawing pictures of the ocean. I LOVE sharks and other marine life so that was always my passion to draw sharks and other sea creatures. I can't wait to see your work some day!
