Though, yes, there are even bigger problems than those with for instance the unfinished geometry of the model, it's also very important to stress the things you're mentioning; so thanks a lot for your contribution!
Even with the big fixes that needs addressed to just make this a finished model, they should also - according to their own goals and what they promised with these new models - be making sure that things like the facepaint hues and other details remain faithful to the original.
One example is the facepaint that goes with the light green hair colour. Before its facepaint used to be a really dark green... Now its a
light green, all the way over to the other end of the spectrum with that colour.

Indeed... And before I'd use the word "skinny" I'd call them "lithely muscular" and "lanky". There's plenty of meat on them, in terms of mass they're at about (or at least used to be with the old model) the same as a human just stretched out over 8 feet... And we all know how ridiculously roided up those humies look.
And the hunch is a primal stance yo...
