That is very nice drawing. Woman, which body is made of plasma, being drained by cage she is trapped in. I really, really like those spots serving as freckles and others as marks that some people have all over their bodys. Waves of thrown energy give me vibe of very messy hair. I don't know what is that cross shaped thing on head is supposed to be, but I guess it fits here.
All of that ties nicely to female curves, that I am not great at describing, altough I will say I like them.
