this really makes me think of "The fury of the Northmen!" Coming from across the sea burning and pillaging, raping and destroying! the brightness of the sky and the flames really make the central figure pop, and the angles of the figures create tension and movement. Very nice work!
I feel like the fire should be brighter and create more of a glow / reflective light around the characters (and a tiny bit more contrast- I was clicking 'next' through all of my deviantwatch art and almost skipped right past it because there wasn't a great amount of contrast and it didn't catch my eye immediately). Just throwing that out there, you probably get more "woaahhh this is amazing!"'s than critique and I always find it far more helpful when given legitimate crit. Other than that, great work!
Great energy. It makes you feel that there are a lot of things happening as it would in a real raid. It actually made my eye navigate thrugh the entire image, as if i was there and trying to figure iut what to do.
