Anyone remember when she was a 6'1 genetically enhanced avatar of death and revenge cultivated by her alien bird parents?

She still is. She just now has a little more moe~.
I personally have nothing against it, I don't think there is anything wrong in giving samus a more human side, and not just be another space marine that doesn't talk cause he's too badass. It may be out of character sometimes, but remember these are just fan-arts, and they are not known to be really faithful to the original material.
