Well it might be a bit big, but with a proper magma paintjob it will certainly look impressive! I like the pose a lot. Not sure how you will be able to fix wings on that thing, though.
Wing problem isnt or shouldnt really be one I would first make the throne for therider and then make a impression for the top of the model where you wish the saddle to go. Using Talc powder as a release powder make a square base for the throne ect (of your going to have a throne that is) then you can mount standard dragon type ones on the throne base and make similar mosaic base for wings wiht the miliput or kneedalite. not only that the base can and will be able to be removed once it has set. Just ensure to remove the relese powder before you re attach when you have finnished
Perhaps paint the whole thing in gloss (bear with me here) then use a cloth and wipe the yellow orange or red paint into the channeled looking areas ? painting small area at a time and
Clean black almost marbled like Gloss surface

then maybe take the gloss shine off by using a mat acrilic varnish
my idea is a wings (a little small in comparative with dragon wings of workshop) and put in with greenstuff…and glue, but I don’t know the result…:sick
