You know, after a while this new style kind of grows on you. You know what, I like it... I really do. I think that you should keep this design. Now all I think you should do now is do a SSJ5 Vegeta (New Design). I think it would be really cool.
Would be cool if every SSJ5 look was unique. Like, since Goku has been lighthearted he could be the Gold standard. And how Vegeta has had dark roots but been reformed could be the salt and pepper. Well rigor could be stay how he is but, instead of just the streaks of black in his hair it could extended to his fur. But, i don't know, it was just a random thought, to set apart NA.
