Yes you should change the tv type because it's not immediately clear that it's supposed to be a tv. It could just as easily be a window of some kind. I like the colors a lot and I like the idea - I think maybe you could be a bit more clear in the details to show what each thing is... like the green thing - is that some sort of furniture for the plugged in head? And the wires... are they electric or cable? You might make a stronger statement if you were more specific.
