Sketch by Andrea Joseph. Whichever theme you choose - remember that you can DRAW really well - it takes time, it's hard but it gets you marks and it helps you PROGRESS. Why not commit to ONE DRAWING EVERY DAY for the first week or two?
I found this task and thought that it can apply to just about anyone! We all have shoes. Simply chuck them on your desk with a piece of white paper underneath and attempt to draw them for some AMAZING results. Tip- images like above take time! Start with basis shapes and make sure your proportion is accurate BEFORE adding shading/patterning etc
