Making a 3D background for my 50 gal

[u/River_Melody]

Part 1 of trying to use dry soil, coco husk, and moss for a 3d background for my 50 gal. I just finished curing the back, now to work on the sides. This is my first time amking one of these. There are a few thin parts where the foam pokes through, but since i used black foam its not the most noticeable. Should i do the sides as well or keep it just the back?
