The Hands of God with a crescent moon.
To my surprise (ignorance) one of the six "Articles of Faith" in Islam is Faith in Angels (link).
Should also mention that not all Muslims accept the Crescent Moon as a symbol of Islam, and I also doubt they approve of a half naked angel.
At this point in time I`m uncertain about keeping the crescent moon on the body (there is a sort of crescent in the tail fins as well), might be a bit too much figurative information...Improved a bit after the second sanding (picture to the right)
The angels` wings and body form the cross, combined with a crescent moon; illustrate the sculptures` title.
