I have a lack of ideas to a Great Taurus conversion… I do have a original Great Taurus model, but wanna convert my own. But I have no ideas, of what models/parts or anything to use at all…
You could also convert the existing Taurus, since you are lucky enough to have one. The best bet would be exchange of the wings against something bigger (like the Balrog wings that I used on mine) and swap the horns against those of a Bloodthirster or Dragon. Add some armor and you get a very impressive model!
