Anime fanart BLOOD+ 2

Here is my 2nd Blood+ fanart. Featuring the antagonist Diva. She's also my favorite character in the series. When I saw the show for the 2nd time and saw her last duel against Saya, I decided to draw a fanart of her in her dress with the bat wings and stuff. I just hope I drew her correctly.

There may be things in this fanart that seems incorrect. Namely her sword, some parts of her dress and her hair... I think. I didn't include her crown/headband with the batwing thingie, sorry.
