I am going to be Constructive.
My Opinions.
Your Focal is set REALLY far right, move it closer to the center but not centered, 3/5 or 3/4.
The Text is on top of the focal like a fat guy at a pie stand, Close is good, but would you want to be next to a fat guy at a pie stand, I think not.
The Flow of the background is going opposite the focal, No worries I still have a hard time with flow.
The focal is a tad blurry, Looks like you did blurring or the render is LQ. Try a little sharpening but Go Easy.
I like the Boarder, Fits the color scheme and idea well.
Colors Flow, but their is a lot of red, try to mellow it out, Mono Tone is not good.
Try a More Aggressive Text and work on Blending it mildly with the background with a similar shade of white as MM's Face.
Great Concept, Keep Working on it, and Try using a Gradient Map or an overlay to help blend all the colors.
I hope this helps, Harsh but its to help you. Not intended to be mean.
