Blood

I have to say, I've been looking through your gallery and while the cosplay itself is impressive, the attention to emotion through expression seems lacking - on your part at least. In the majority of your pictures, while most of the characters you portray have a stern but deep expression, even when not smiling or scowling, you just seem blank. Likewise, the one on the right of the picture actually seems to be silently roaring, but it just seems as if you have your mouth open slightly.
But as I said previously, the cosplay itself is impressive.
