Biased.
Very good animation, and very good music. However, you have made this video without thoroughly study the powers of Superman. First, did you forget that superman has heat vision, or just decide not to put it in there? Second, did you forget that superman moves at the speed of light (hence, the ability to outrun the Kamehameha wave)? Third, if superman just flew into deep space, where Goku cannot breath as a super saiyin, fly into the sun and absorb its powers, he would roast your boy Goku.
