Looks promising, though id suggest using a more egyptian symbol, the pentagram is western.

Ankh
Symbol of eternal life. The gods are often seen holding an ankh to someone's lips this is considered to be an offering of "The Breath of Life". The breath you will need in the afterlife.


Amenta
This symbol represents the Underworld or Land of the Dead. Originally it meant the horizon of the sun set. Later, it became the symbol of the west bank of the Nile, where the sun set and also where the Egyptians traditionally buried their dead.

Ba
The Ba is what we might call someones personality. It would leave the body at the time of death. During the days the Ba would make itself useful, at night it would return to the tomb. At this time, it would look for the person to which it belonged. This would be the mummy, however, often the egyptians would supply the Ba with a statue in the likeness of the deceased in case the mummy was lost or damaged.
