Most comic book characters with these kind of costumes are hard to cosplay because usually the outfit is drawn as one piece.
You got the perfect blue material for Nightwing's outfit. It's accurate and reflects light like the comics. All of that definition in the drawings are virtually impossible to re-create in real life.
But you come pretty damn close!
The weapon props are really clever too. How'd you get that idea?
My one criticism with the costume is the eye mask. It's too bulky in my opinion and should be almost flush against the skin like the rest of the outfit for the sleek look. It's really the only thing I notice with this.
The hair's styled right. The pose is fitting.
If only you could get a higher location for the shot, or a place concentrated with taller buildings to make it more like Gotham's setting. Or maybe.. more shadows? (I am the night )
This I really enjoy. The costuming is amazing and I love how it looks on you. It suits you and I love how it looks like a one piece. It's really hard to make an outfit look so accurate like yours. The blue is amazing on the outfit. The lighting makes the outfit pop even more. I love the prop you used as the weapon. Where did you get it actually, plus did you order or make the suit? In a way it doesn't matter because it looks amazing on you. Again I love it and keep up the good work!
