For almost a month, I couldn't finish this. It sat so quietly in my WIP folder, while lots of new WIP being finished. So I decided that I should finish it no matter what. The only problem I'm facing back then, was the coloring style. How am I supposed to color him in the same style as Asazariel is I didn't even remember how I did the coloring. So the only answer is, new coloring.
So I changed the coloring for Asazariel to match up with this, so I could put them in an artwork, side by side.

I didn't even stop for sleeping in order to finish this. That's why I love/hate this artwork.
