I like your work mate! But again there is always one thing messing me up... here it is kinda the color. I dont know, in some parts it looks too desaturated. Cuz when you have all that powerful lighting blasts going on, I might would add at some parts more saturation. Apart from that awesome work!
I think a border would be good, but I was raised on borders as a requirement. I like the depth of field, but the eye looking thing in the top right is weird to me.
