Dragon concept: Great Highland Shrieker

It’s been some time since I’ve done one of those- but I’m back with another dragon concept, this time based on a barn owl. :D 
The name is, again, inspired by the ‘How To Train Your Dragon’ films/series, so that’s always fun to think about.
I think I was mainly focusing on the rendering of the creature rather than on its overall design. It looks simple, just an oversized feathery beast with a beak and two pairs of wings- 
My rendering technique was something I’ve been trying to change up for some time; to simplify it and maybe give myself a bit of a change in art style.
