@Gyrruss - I really like your last 4 costumes a lot in comparison to the first two. I think it's due to the proportions fitting more nicely rather than something so large armor (mad bomber), combined with a smaller helm (scale helm). With the green tabard, I feel like the helm is sort of out out of place, but just every so sightly, since it is it isn't as bright as the tabard and shield.
The kat costumes are adorable. o3o
Your friend's costume is very nicely done! They really pulled off the maid headband! Hahaha! But seriously, it is *really* appealing to my eyes at least!

@Fallconn - You are sexy and you clearly know it. ;) Just... Yes. I don't want to know how much cashmoney you dropped on those, but you did good. Reeeaaaal good.
