background is fantastic imo but the render isn't well blended and is low quality.. also this looks like you left room for text and didn't put it there..
It's actually not low quality, but it did lose some during the sharpen (which I reduced a lot already..) Anyway I'm giving text a rest, I've been using text too much lately and yeah.
wow the fx is very cool.. really love it mate.. tweak with the flow a little more and text it to notch 100% KIU!!
