YES!
This is more like it.
You’ve totally nailed the assignment. My only minro note on this assignment would be too have made the connector or plugin part of the cord in focus. There is almost always something that is more interesting in photograph than the rest. When you’re using shallow depth of field you should feature that thing… In this case it’s the connector or the plugin. I’m not sure what it’s called …
Also keep in mind your focus will look different depending on how you look at the image. The smaller the display/screen/print the more perfect your focus will look and vice versa. If you want to geek out on this checkout something called the circle of confusion: http://en.wikipedia.org/wiki/Circle_of_confusion
Anyway you get the idea.
Nice job here!
