Honeslty, I think the head of the Giga needs to be shrunk down a little. It's about the size of the body even! That would make it severly front heavy, possibly forcing it to have a more erect back posture. And if the tail was longer, it would help with that problem, but it would stay severly front heavy. So I'd say lengthen the tail, and make the head smaller.
