Shut up about getting rid of the film, and get back to topic, or leave this topic, okay?
Anyway, one thing I never understood was why would it have more human DNA than the aliens if it was born from the queen? If anything, it would have the same DNA as her since she wasn't fertilised in any way.
I would have said keep shape mostly the same, but make skin tougher, more like the exoskeleton, and get rid of the stupid bit of cartilage on its nose.
