Advice? Frag layout

So I'm looking for some input from you fellow reefers. Today I met up with a local reefer and he gave me an awesome deal on some new corals. Got about 14 nice sized frags of a variety of sps and lps. They were all fresh cut from his tank as they all needed trimmed back. I got home, glued everything down to some small rubble rock pieces (not a fan of plugs) and threw them in my 20gal QT/Frag/Misc tank to let the glue set up.....And that's where I'm stuck. I don't know how to move forward with putting them into my main tank so they don't look like I just threw them wherever. What are some of your tips/tricks to make an eye catching scape? I know the requirements of the pieces, but just want to make sure it looks aesthetically appealing. No one likes an ugly tank
(the pieces will need to be glued down, so it's basically a one shot deal so I want to get it right)
Let's hear from all you fish tank interior designers

 

@Turbo's Aquatics, I actually was originally planning on leaving them in my 20gal for a bit, just to heal up before putting in my display tank. But the guy I got them from suggested not doing that and said my main tank would be more stable and to put them in there.

@violet21chewy, how would I go about doing a semi-permanent set up? I can't just set them in there--flow and crabs/snails would knock them over. I've already ran into that a few times before.

 

So I have a slightly different question but don't want to start a new thread for a quick questions. Will sps/lps frags be okay on the sand bed for a day or two? I'm running (2) 165w led units, one of the units being right over the area of the sand bed. Tank is 24" tall and light is about 8-10" above water and nothing shadowing the frags. Had an issue with my nem so I had to switch gears for the night. Will my frags be ok for now?
