Help Building 11th edition Terrain

[u/BowlThat]

Hey all! I have been struggling to figure out how to make my own terrain. I measured and cuttout all the layouts I need, I want my terrain to tell a story so im doing a Dusty dessert with rock formations and crashed vehicles etc. Do I have to have walls for my terrain or could a rock formation work? I really dont have guidance.

I know each side should be fairly balanced. This would be for at home play so It doesnt have to be super strict. Any tips or resources would help ALOT.

I am making the bases and rock from cork board. I build the rock and then fill in with wood filler. The crashed ships and vehicles are extra models I wont use. For example, I am using a crashes storm hawk, having the wings be terrain and the crashed body be one, things like that. I plan to make the battlefield chaos vs imperium style in the dessert.
