Dots, Lines, and Some Shapes

For the umbrella: In both compositions, the elements correspond pretty exactly to the basic elements of the object in the photograph: the handle, the two parts of the umbrella with the tie in between, etc. Since the sharp shadow is a pretty significant part of the original photograph, I'm surprised it wasn't acknowledged in either composition.
For human movement: I find the dots hovering in front of the screen interesting. From your description, they seem to represent not something displayed in the source image but rather the concepts that we associate with the laptop and what it does. Since you're not merely mimicking the image with simpler visual elements, you must be assigning meaning to the simple shapes used in these compositions.
