These grabs are from the Manga series Legend of the Four Kings. This is an excellent series, unfortunately the end is a little lacking, but the rest of it is brilliant. I loved the subtle humour in it, go out and get it.
If you are curious to know what its about, the series centres on four brothers who also happen to be dragons. Typically, they don't actually know they are dragons and there are a pile of people who want to capture the dragon power... Like I said, go and see it.
