That red moon framed by red magical particles reminds me of an existance annhialating demon known as Garo, who can destroy a world just by its full presence. Seeing this picture, it looks like shes summoning the Eye of Garo. A bad omen indeed.
The composition is superb in this I love the smokey atmosphere you present here and it mixes well with the particle effects floating around. The colors show quite well and I love the color palette, building an excellent foreground, middleground, and background.
