Just FYI, we're working on gryphons at this moment, they need update a lot more than any other species right now. I can't promise any updates on dragons soon. Liandralithe is right, this is pretty big amount work with kind of low priority comparing to gameplay updates. Besides this, dragons were the first who got their base improvement when deviants were introduced. Before starting the new turn of improvements / revamps or anything else in this field, we need finish with this turn for the main six species - gryphons and cockatrices don't have their deviants yet.
Also please remember that this is a fantasy creature and there's no "correct" anatomy for it. All of us have own preferences in creature design, but when you think of proportions, remember diplodocus' head size and giraffe's neck length which is not enough even to reach down to the water. Or how about this creature as a direct opposite? :) Nature is quite intricate about proportions, so until the animal exists in reality, we can't say what proportions are correct for it. There is an explanation for our dragons' proportions taking into account our sci-fi world and their background (remember that they fly, and not with magic - they can't afford big neck and head but need well-developed muscles for body, large chest and rigid pelvis), but it's not a problem to find an explanations for a creature with different proportions as well. It can be found for pretty anything except the things that are purely out of logic like extremely cartoony creatures.
As for the pose, this is just a matter of the angle of view. It's a flat profile, so paws will be on the same line when they are touching the earth. Here's a 3D render that shows the same angle. Probably the confusion appears because different species have a bit different angle, and I totally agree that some unification will benefit the dragons here. There's a vast field for improvement, of course, mostly for the expression and originality, and maybe lighting and texturing.
