Hello Ayesha,
Welcome to the wonderful world of visual creation. I am excited to hear about your plans to put your imagination to work and create a webcomic for others (including myself) to enjoy. I want to inspire you to help you achieve that goal and more in your future.
When it comes to art and style, the sky is the limit. As you are creating, let your imagination soar. Art is a form of individual and unlimited expression and possibilities. So as you practice, let it flow frequently and freely. Buy yourself a sketchbook and lose yourself in your imagination then come here and develop your knowledqe of gesture, structure, and anatomy by practicing daily in short sessions (preferably 30 minutes) to give you an idea of those things.
Stay consistent and let us see your progress. We're waiting anxiously!
