Heartbreakers: Art breakers

Looks like someone isn't very good at hands! Or heads!

Edit: For those of you who like less terseness, here's the blow-by-blow!

1. Surely statuesque Sigourney would have a head on top of her neck, rather than next to it.
2. Ewww! Web hands!
3. This is just awful. It's as if the designer, exhausted from airbrushing the fake arm in had no idea how to end it and just gave up.
4. What's with the huge hand?

I would have put in #5 Sigourney's blurred-out shoulder, but the other blunders kind of crowded it out. Sorry for the small size; this is the largest image I could find.
