The King of Hell

I haven't been posting for a qiute a long time, but I finnaly learned how to draw dragons and humans properly. As you can see I improved my art and my art style evolved. This is one of my not-so-old pics, so I will be submittinig more images soon.
This is Satanic Dragon from my fanfiction called HTTYD 2,5 and he is main villain in what I like to call ,,Season 2'' of this story.  That ,,ghosts'' of dragons are simbols of Hiccup gang dragons: Meatlug (brown), Barf&Belch (green), Toothless (purple), Ice (OC, light blue), Arrow (OC, light green), Hookfang (red), Windshear (light grey), Stormfly (blue)
That thing below Satanic is Dragon Medallion - an mysthic arifact that can destroy any-sized dragon.
If you want more informations, you can ask me in comments.
