Volvagia looks gorgeous...! And I love the colors. A thing that did stick out to me was Link's stance, though--it looks pretty nonchalant for a guy who's just had a dragon pop out of nowhere.... Still, this is awesome. The detail and textures!
Ah, this looks fantastic! I love how Volvagias eyes look rather challenging than evil. His hair also looks very good!
Though I've never played the game, I really love this character, because I've read the manga, and I really liked how the illustrator portrayed him as an old friend of Link that got possessed by evil. It really hurt Link emotionally to kill him. I think you expressed that sentiment very well, that Volvagia isn't just another evil boss but something Link recognizes from past times, and also his hesitation to act can be seen clearly.
