Well! I don't know if my comment is going to be read or not by the TC, but, if it does.. I'd be happy to make some critique. ;D
Anyways, I'm very impressed by the amount of work that you put into your gauntlet, sword, and armored--shoes? That takes a good amount of dedication and I guess, though, to be nitpicky, you could probably do a tad more work on designing the top portion of the sword. (BUT .. like I said, it's just me being nitpicky!)
Those are the parts of the cosplay that I liked the most.
When it comes to the teal-colored fabric of your choice underneath the armor, I feel that the texture of it doesn't sit right for me with it and it seems like you'd be a better more "shinier" appeal of having something else. Probably try to find something in silk? If comfort is an issue, then, maybe you might have to layer one sort of fabric over the other.
I'm pretty sure most people already commented on how you might fair well better in a white colored wig, and I agree with them.
Last but not least! The base armor and shoulders, honestly.. well, I think you did well for what you did! Trying to cosplay as a heavily armored warrior isn't that easy at all and it looks better than other "Redeemed" Rivens out there. Sure, the main thing I'd probably improve on is giving the armor more of a shaded/rugged look to make it more authentic and battleworn.
In any case, I know overall I'm just kind of nitpicking.. it happens! I'm kind of a cosplay elitist.
But, I really admire your dedication to your cosplay. It's nice to see people try and challenge themselves to cosplay the better outfits rather then the "Oh, I can buy this from a costume store and say it's this-or-that cosplay!" So lazy.
Hope to see more updates on how your cosplay went!
