Hi again, I decided to appologise for my comment before. I have been comparing the picture with some Alduin's screenshots and, well, it could be Alduin, the horns should have been bigger, there are horns and spikes actually everywhere on his body, even on his wings, he kind of looks like if he wears a dremora armor, his body is just a lot more detailed than any other dragons. Also the eyes, he doesn't have pupils in his eyes, just.. red. I am sorry, I am usually not a critic for anything, but he's my favourite dragon (after Odahviing) from Skyrim, so I feel like I should defend him. It's a great picture, he just doesn't look Alduin-ish enough for me.
Well, I played again Skyrim , and yes, possibly I have drawn wrong, in my screenshot did not look good Alduin's face, and I had to invent some parts of the face and the body. I thought this was the problem. Sorry if my drawing offended you
Nice Job on this, by the way. The Detail is something to behold, here.
