You misspelled "Protective", erroneously placed and styled the blue stripe, didn't include "Homeland Security" anywhere, didn't include the ICE badge, didn't put a number on the vehicle, and the logo is the wrong size and in the wrong place. Even dealing with the standard unlocked Buffalo, there isn't a whole lot realistic about it. But, a skin is a skin. (For reference: this rating reflects an earlier version with these mistakes, the current version has some improvements.)
One, try using LEDs that have clear lenses so they're not as easy to see; two, can you use something better than three reds on the rear hatch? Two blues in the back window?
They're real-life brands, but you just stretched some logos out to fill the truck. Try using real world designs that incorporate logos, or put realistic ads on the sides.
