Heh, coulda fooled me, anyway it was just a thought since all the times we see the Heroes of Both Marvel and DC they have a facial expression - sometimes it's a scowl, other times its rage, a grin...a mad grin something like that. Everything else is just perfect.
Like Seriously! Do you have a messaging system that tells you if someone has reviewed your artwork?! xD I also like how you've done her face and smile/grin really makes the artwork perfect with the visor. You should draw more grinning characters.
