I'm loving it!
I'm really loving this piece of art here. It brings me back to the opening of X4, like how DarkHado already said. The expression on X's face, the crater under X's foot, the small rocks flying away, the stance... Really good attention to detail with great use of blue-ish color pallette, which makes it calming and nice for eyes. Yet it still shows how powerful and immerse the charged shot is.
As a Mega Man fan all since I played Mega Man X, which is my first game ever, I really have to say this falls under the category "best Mega Man fanart I have ever seen" for me.
