Been playing a lot of Genshin Impact, but I'm not that far in the story.
The only important part though is that when looking at the prompt, Stormterror was the first to cross my mind.
Dvalin is a very beautiful dragon. I wish I could do him justice when actually drawing him.
But, have a decent sketch of him.
