Looks good. My only recommendation would be to try to get it to move into the rockwork. I don't think you need to remove it, just makes some space away from the BTAs and allow it to move freely into the rocks.
Unlike magnifica that like to perch on the top of a flat rock and extend their oral disk up and over their foot, gigantea typically like use their verrucae to keep their oral disk low, clinging to the rocks and hiding their foot.
