If it were an LSSJ 4, instead of the typical Red Fur, I would say it would probably be cooler to have his fur to be Golden, to be a little more unique and to better show off the difference between a normal SSJ 4 and an LSSJ 4. However, that's a LssJ 4 form, not an LssG 4. So, if you WERE to do a Legendary Super Saiyan God 4, I suppose it would be better off making him have dark Orange fur, but with red hair and the typical SSG aura. No pupils of course.
Just a, general idea, if you were to do it of course .
Broly is a Legendary Super Saiyan and possibly can't be a Super Saiyan God.
Other than that, still a good concept idea.
