I like how this letter is incorporating a human element, but is not fully made out of the hands and arms. If it was simply just a letter or just the arms I don't think it would be as interesting. Mixing them together brings a new aspect to the type.
The white space caught my eye first. The small type along the top and in the bottom left corner balance this cover as the image weighs it down. I like how the image is treated, printed in black and white and cropped so that some of the figure isn't visible; it peaks intrigue.
