Cover of a comic I may or may not work on since my Immortals comic is of higher priority. Just in case, I'll explain the main story. The character in the center is named Azazel, meaning sin, or "brought sorrow when birthed." Angels are born with primarily white, brown, pastel, or golden wings (though golden is seen as royalty or wealth).

Angels are never born with black wings, but Azazel was, and is therefore seen as a "sinner" or a curse, since only fallen angels have black wings. Therefore, he's often bullied and beaten, mainly by the angels in the top. From left to right it's Aria, Steel, Idis, and King.
