Once in the tank with plants and substrate it will look more realistic, not that it doesnt now. It may also grow a coat of algae which will help it blend in more naturaly. Either way, i wouldnt do anything else to it. I think it looks great. I have made a few of these my self, as well as bought store made ones, and they never look that great until there in the tank with sand, plants, wood, ect...
