There is so much beauty in this piece that I almost can't think of what to say about it! But, I'll say something anyway. I HAVE TO!
I've always loved X's Falcon Armor. ^^ I'm loving his pose a lot here! And I can see just enough of his face to be able to tell that his expression is an intense one! But somehow, I think he looks quite mysterious this way... I love that!
I must not fail to also mention that the way the light is shining on his body is just... perfect, if I may say so.
The celestial background with the galaxy and the stars adds a neat touch to the image! I think it kinda gives this a very "Final Battle" feel to it.
Amazing job!!! X looks very bad-ass and very cool in this lovely piece!
