Honestly love this.
I like the use of the almost monochromatic red colours with a good focal point. Also I enjoy the additions of the information text to fill the blank space. This piece kind of makes me think of Iron Lung with how a map would look for that 'Sea of Blood'. :)
I always appreciate art that tangent UI in some way, i'm probably biased though as a I work as a UI designer, haha.
Well done!
