Negative space of another persons piece

The shapes inside of the picture are very well drawn. I also like how it is very little black in the background so it creates interesting shapes within the negative space. Especially inside the hand with the wrinkle lines and finger prints. There is also a lot of different things within the picture which makes the drawing interesting. Such as the snow and rain, or the meteorite and the Leaning Tower of Pisa. There is also very well done visual hierarchy. For example he makes the hand appear up close and large. There is also a lot of detail in the hand with the finger print, but with the leaning tower it is farther back because it is up higher on the page. It is also smaller than the hand with less detail causing it to look further back in space.
