Beautiful costume, Nienna!
I'm no expert, but as a fellow cosplayer I can give you some constructive criticism if you like
First and foremost a wig makes any costume 100x better. It just helps complete the whole fantasy feel rather than risking looking like a girl wearing a costume. It helps you 'become' the character!
I love all the detailing you did, especially with the jewelry. I mean, that piece hanging from your bra--STUNNING! Did you make that? I love the little skull on your necklace. You didn't neglect the Rit tattoos either. Excellent work! Unfortunately, like others have said, the photos don't really help to show off the intricate details of your costume as much as nicer ones could. They're better than some GW cosplayer photos I've seen, but still a little blurry.
But yeah, I see nothing wrong with your costume. I even brought up the in-game model and flipped between the art and your costume, and you got all the details! I'm impressed!
The only other thing I can add is more of a personal preference, but I'll add it here just because I've wanna vent lol. There's so little GW cosplay out there, and it's really sad because it's such a great game with great characters and so many beautiful designs. However, every other cosplay that's made seems to be a Ritualist. (Or Eve...ugh, please no more Eve.) Maybe it's because I'm not a jewelry and bead person, lol, but I'd really like to see some other characters and classes represented by the fans. Absolutely nothing against anyone who wants to make a pretty Rit costume, it's just my personal wish for more characters
(have you seen the Charr? woooooooooow!!)
