Tengil and the Dragon Katla

There's this book written by Astrid Lindgren called 'The Brothers Lionheart', and while I've never actually read it, I know the story and I have seen the Swedish movie or short-series based upon it.
One day, I just had this picture in my mind of Tengil, the main antagonist and his great dragon Katla, whom he controls with a horn.
So, I put it to paper and voila, a drawing that I'm actually very happy with came out!

I also have some other pictures from the same movie/book, so maybe one day or another I'll give them a go and try drawing them!

But for now, what ya think!?
