As many members said, practise more will definite improve your skill. If you like to take insect macro photography, I would recommend Singapore Botanic Gardens is a good place to start from. Visit the place more frequently, understand the lighting, insect behaviours and look out for open space greeny background. Usually insects are visible in the open and inactive in the morning due to the sun is not so hot.
Lastly, if you cannot get the shots to your expectation, post your shots here to get feedbacks.
