Overall I quite like it. The concept IMO is nice though you do have two focal points with the face and the lighting bolt, I still think they work.
Something seems just a bit too chaotic though, I think by enhancing the depth would improve this. Darkening and blurring some areas on the edges would increase the concept of depth.
Also the bolt seems a bit over sharpened, or just distorted at the top. While it does seem you are going for a sporadic look since it is a bolt, that part just seems distorted imo and not natural for a bolt.
again overall I like it, adding text could definitely improve it, but if you are unsure of what to or how to add complementing text I would leave it alone lol.
