This was a hard one... I can agree it looks a bit strange, but it's hard to pinpoint specific issues.
Could you post one with a neutral (maybe gray or black) background instead of the image? Because I think it may be a matter of "mismatch" between the image and the other content.
How many fonts have you used? I get a little bit of the feeling that there are to many font variants.
2015 looks way to weird, kerning please!

It's probably because the font has monospaced figures?
The two yellow texts half way down, to me the right one looks as a larger size... it's proably an illusion, but why? Because of different number of lines? Or because of background image color?
Move "100% Unofficial" closer to "us"? Or is it in line with the b ascender?
I think Issue #1 should be in line with the edgeds of the barcode in some way, now they look centered to eachother.
Could you maybe post an image with guides visible?
