Help me better Aquascape my shallow reef tank

[Gore15]

I have a reef tank of 85x35x20 (cm) and now I want to do a rearranging of the rocks and better aquascape it. I have more rocks to add if need be both in small size and bigger. I inherited this tank and have been doing my best to keep it as good as possible and my plans are as follows for it:

 

• The right side next to the filter compartment I want to add more sand (turn it like a small under water hill) and plant the 5 mangroves I am cultivating.  as you see there is a stone background right next to filter compartment. That is the area I want to add the mangroves.
• There are about 13 corals and I am going to get at least 3 more (chalice, another montipora and another euphilia) to place in the tank.
• I have 4 small cuttings of the following macroalgae that I am thinking about placing them in the right side close to where the mangroves are.
  • Cryptonemia Crenulata
  • Caulerpa taxifolia
  • Codium sp.
  • Gracilaria Curtissae

 

What would be your recommendation for aquascaping? Should I add more rocks? Remove some rocks? Put them all next to each other? Any recommendation or share of wisdom and experience is very very welcome.

 

PS: I put a small video of how the tank looks like here: https://i.imgur.com/0YTNytu.mp4 as well.

I have toyed with idea getting a shallow tank but never actually went through to get one. I have however spent lots of time thinking how I would aquascape one. My favorite ideas I came up with were

 

2 island: bommie style with lots of negative space and one island is smaller than the other. Lots of sand bed space open allows for a more natural feel.

 

Valley: basically two elongated rocks positioned to make a valley. You have more space for coral but it doesn’t look as “clean” IMO.
