It's all about the lights, and focus. Try to take a shot like if you have multiple lights and it drop light effect (like shadows) at your camera and in picture it seems clear then move the light or the object to the other side, well there are so many things that we can say and that we need to think about but the problem is we don't have any idea how that object you want to shot and how's the situation so generally just try to make good picture, when you aim for a good picture, ideas automatically comes in mind.
