I've started putting together the environment elements of the seabed, including a sign, bottles and a plastic bag (which still need some texturing work!). I want there to be a large cluster of this plastic, but I'm not sure how to make it look like a lot more, I might have to start building a few more other plastic elements to bulk it out, or use some abstract or 2D methods to do so- or keep duplicating and bulking it out!
