I find the background and everything else looking fine, but the image itself is not really, well blended?
I am not quite sure, are you trying to make it pop out, or in.
On the side - right, you blend the background onto the image, but on the left side, you made it pop out, which is kind of weird.
Personally, I think image was somewhat not fitted for that theme, just sayin'.
As for the font, I think that was okay, but maybe do some little effect on it.
As for the flow, it was a bit off, one side is dark, but the image is light, while the other side is well you know.
Well this is my opinion about this artwork. c:
