The head of Exia - Mobile Suit Gundam 00

Recently, I've become a fan of the mecha designs from MSG 00. I just like how detailed they look.
And so, I've decided to try my hand in drawing mechs. First I decided to train a bit, and draw a Gundam head. And what could I pick other than the Exia?
And so, here it is. Not really exactly how Exia's head looks, cause I couldn't get the hang of it's size... But still, it's my favorite from my recent drawings.
