>>6453307>It looks great because that's how they're supposed to look>I am incapable of making aesthetic judgement on my own, and only think things look good when they're accurateGod, fuck off.
Also, Dinobots look better in silver. Fuck accuracy. Look at how much more the detail pops on pic related. Also, their color has nothing to do with whether or not they're painted. Almost every Grimlock is cast in this awful, cheap, gray, swirly plastic that is painful to look at. They should either use higher-quality shit (like the gray plastic on FH Gunfighter, which is pretty smooth looking) or fucking paint it. Most of the Dinobots have such simple transformations that they would make pretty decent candidates for an all-over paint job.
And since you're an accuracy-fag, take a look here
>>6450944, the shading on Grimlock's gray parts clearly indicates a kind of metallic sheen, so a semi-gloss gray paint job on a Grimlock would be both accurate AND look better than the milky, flat, garbage plastic he's usually cast in.
