I like the concept, but I just can't se why you had to draw the needle and the backround with such little effort. Like, come one, you could have drawn a needle that doesn't look like a flat surface, because I see that you do know how to shade.
The background is just a blurry mess to me, and those lightning-thinges are just ... Ugh ...
I liked the picture overall and the hair, eyes and neck are really well done. Good job! Just don't wast a good picture next time and spend some extra hours to get it all right.

That is one big boobed robot nurse XD
