The eyebrows. They are all mixed up. Why does he have yellow eyebrows and blue eyes when he is normal and pink eyebrows with normal eyes when he's SSJ? Not to mention that both models have USSJ style hair whether he's SSJ or not.
There are two models. There's a SSJ and a normal sayian version. The normal version has pink hair, but it has SSJ eyes and eyebrows (the typical blue eyes and blonde/golden eyebrows), while the SSJ version has SSJ blonde/golden hair, but normal Trunks' eyes and eyebrows (normal eyes and purple eyebrows). Just look at the picture of Trunks on the top of the title bar of the forums, and you'll see what I mean.
*edit* Nevermind, he fixed it. Sorry. Open mouth: insert foot.
