Sketch is a nice tool as it allows creating awesome design techniques such as the blurred background or the double exposure. I`ve found some interesting effects and techniques which can make your design dynamic and exciting in the following article: http://computoolsglobal.com/blog/how-to-create-dynamic-and-exciting-design/
