You are going to combine realistic drawing with highly decorative pattens to create an interesting contrasting effect.
Start with finding an image of an animal or an organic object.
Look for a picture of the entire animal/object (not just a head or a part).
Furry animals can be chosen if you are comfortable with drawing realistic fur.
Best choice is an animal/object with many parts and details - it will make it easier to divide them into shapes - reptiles, insects, sea creatures, etc.)
