Cortana is such an interesting character to costume. There's no in-between with her, you either hit or miss. This build certainly looks like a HIT.
More progress pics please.
* A * Im in LOVE with your "honeycomb" details on the dark blue part!~ and tinsel is amazing for Cortana costrumes (wigs or on the suit) 8D I used a black holographic for my wig was a black and blue mix.
Cortaaaanaaaaaaaaaa~~~~!!! XDDD
You did such an awesome job. It was so cool to see you come around the corner at the con and BAM! There was a Cortana! XD And you're not even done yet! You can only get more epic from here. We totally need to get dressed up again so we can record our antics. Phoenix ComiCon wasn't long enough!
Really good work! I'm quite impressed, especially since I could never make something so epic! Though to be fair it is a bit creepy seeing you with blue facepaint and hair lol Great job!
