Really great! In all honesty i have never liked Rodan but some of all this fan art, yours included, actually does spark a bit of interest. One of the thing G2014 did great is the scale and cinematography, and if Rodan looks simmiliar too that he could become real a visual wonder.
As for Ghidorah, seeing as you cant really see much of him, its kinda hard too judge. But the bit we can see does look very nice!
Mothra, being my all time favourite kaiju, is the beast i cannot wait too see. And like with Rodan, she really comes out great and i would gladly accept something like that for her design.
