First of all, that Turles/Tullece upside-left wasn't drawn by me (I think it's obvious but I'll say it anyway...). It's from a concept art from the OVA "Plan to erradicate the Super Saiyans", included in the game "Dragon Ball Raging Blast 2". Ah! And the screenshot of Goku in SSJG... is what I've just said: a screenshot from Battle of Gods.
And now the question: What color suits him the best? XD I can't post polls so I ask you here... hahaha!
