Opinions on Hardscape Layouts

I’ve been playing around with these hardscape for a little over a month now, slowly saving up for a CO2 system and good filter in the process. Looking for opinions or suggestions on a few of these layouts!

They’re made up of four main pieces of dragon wood. Then I have four large and three small lava rocks which fit in some layouts and don’t in others (especially when trying to leave room for planting.)
