Drawing for cosplay ball

I'm going to a cosplay ball this Sunday (OMG!!!) and last week I heard they'll be holding a fanart competition for which the theme is 'ballroom'. I've been trawling through scores of images that came up when googling the words 'cosplay' and 'ballroom'. Finally I decided on one of a girl in a (red) dress dancing under a fairly big chandelier. I've enhanced contrast rather considerably over that of my original HB pencil drawing. I'm not expecting to win or anything. (I just wanted something to take with me to show I'd at least put in put in some kind of effort.) All I need now is some cosplay gear to wear - and to learn how to dance! Anyways, let me know what you think. (Here's a link to the photo that my drawing is based on ... https://mostflogged.deviantart.com/art/Ballroom-Dreamer-Roxy-Homestuck-484330843 )
