Just quietly, disagree with Abnegation regarding the black and white tag. Beast contrasting to say the least...
What irks me isn't the colours, except for the solid white and grey outline of the people, the white outline is too thick and draws focus, and the grey is too dark, again drawing focus.
The other irk is the C4D use, it is nice and subtle over the tag, and then the right side is like a dump of C4D. Try ease up that congestion and try to keep the flow happening or simplifying it.
Also, the tag seems a little low quality, C4Ds could be sharpened a bit more, or less or something and the background could use a tiny sharpen as well.
Besides that, the tag is beast, colours are incredible and the contrasting and sharpening of the focal and general composition of effects (bar mess on the right) is awesome.
As a general note, watch out for your quality because like half of your tags are losing quality from being oversharpened. First 3 are prime examples.
