2) 3D type that creatively uses negative space within the letters! The type ebbs and flows throughout the piece. I like that color was not added to the piece so we can focus on the fluidity of the type. Light and shadows lend plenty of visual interest.
I think of an iceburg when I look at this for some reason. It may be the overall shape and angular design of the letter, or it may have something to do with the cool colors used in the design. I'm not sure.
