1st time DIY background

[newguyonblock]

ok so thanks to a previous diy project i decided to make a background and heres what i got so far



sorry i went to go upload more but for some reason all of my pictures are now missing anyways that's what i have to the left side is a cave that the fish can swim through in the middle will be a waterfall which will not be seen until submerged so lets hope i get it right the first time and to the right idk what to do to it yet any suggestions

appreciate any criticism as long as you tell me how to make it look better

also i will be using drylok and cement add in color to create definition
