the ssj2 would be easy enough to render of course his hair and left side will be cut off, ssj4 would be a little more difficult nigh impossible without cutting his legs off unless you wanted a regular sig. What kind of sig do you want i mean details, i know you want it vertical, but what else? or are you just asking for renders?
it's cut out of course as it is in the file but if it is just a render you want and not a sig...
