Need some direction.

Hello all,
So i have a project i am planning to undertank and im looking for some help from folks who have under taken the task themselves of building a rock wall insert.
My tank is a fully stocked 25 gallon custom made aIo that looks nice the way it is but i feel as if im limiting myself on coral placeability as well as viewability.

My goal is to have a 3d rock insert that takes on the back wall and the left side of my glass allowing my to have 2 viewing sides as well as more open space on the right hand side for for a more natural reef wall drop off look.
Ive only done such a project on reptile tank and i have no idea where to begin to make this reef safe. Here are some photos of the tank currently to help you folks visualize what i have already and what im looking to do.

Thanks for the help in advance.

Wow! Looks like a thriving tank! At this point have you considered upgrading to a larger system. I think a rock wall is great but you may end up shading more corals than you'd actually be gaining in real estate.

Looks beautiful already.

Sounds like a great project for a second tank!
