The smaller a tank gets the more difficult it can be to get that aquascaped look you want, however you can take the bits and pieces which you like from other tanks and incorporate them in yours. Look at adding caves and overhangs for fish to hide in. Add some branch or shelf rock to help create this. I see you have a reef ready tank, so you could also do the minimal rock look in the tank and keep some of the rock in the sump for filtration. This way you have more room for corals to grow out.
In the end it will never be perfect and you will change it over and over again until you smash a beloved coral because you couldn't get the scape right and decide then and there to leave it alone Not talking from experience though...lol.
Just have fun with it as once you start adding corals it gets harder and harder to change.
Look like a pile of rock than aquascape. You can choose some big rock and make caves in between/above to allow hiding spaces for fish and water flow can get through them.
What kind of coral you plan to keep? If SPS you can get your rock like 1/2 tank's height or less to allow room for SPS to grow upward.
If for Zoa and Paly I would get the rock as tall as I can, but when you get corals you might have to change/take out some rock.
Structure wise this looks better but it doesn't look very stable. Rocks seem to be balancing on each other. Any major flow and they will fall over. It is a little too tall too, however if you plan your corals out right you may be fine...
Consider tossing all the rock in your sump and purchasing some VidaRock. It is pretty inexpensive and you can drop it in and have a great scape with plenty of coral mounting locations. Bonsai | Cerameco
