First of all you should read the detailed Spot description and the instructions. Think about every task description separately and pay attention that you finish them carefully and completely. The task descriptions can vary from case to case! If you're not sure how much text is needed, make it rather too detailed than too short.
When taking photos or making videos you should make sure that they are not blurry and well-lit. Details should be clearly visible. If you need more feedback please contact our support.
