You could easily crop the top third of the tag off and it would still look good, if not better, because the render is too small in such a large sized tag.
Also the render pretty much just looks placed on and then left, so blending is definitely needed.
The colours are also randomized, there seems to be no adjustments really except the red/blue.

Don't mean to sound so negative though, just it looks like you've just started the tag and then left it.
