Get lots of artist responses done and write about different processes. Make sure you show development with your work and write about how you ideas change. Experiment with different media to show variety in your work. Make sure you include at least one observational drawing in each project just so it shows that you can draw. Have fun with your work and just go with the flow. You find your style along the way. Also, pinterest is an absolute life saver for ideas and saved everyone at GCSE and is still saving my class at A-Level. Don't worry about it, you can always ask for teacher's opinions
