I'm loving all the focus on X in this game, including his totally different, almost doll-like art style combined with elements of X's appearance in the Mega Man Zero series (mainly the halo and his eyes).
I wouldn't ever want to see this style employed in a (perhaps not, at this point) theoretical X9 or other mainline X game, and several elements of his characterization in this game are inaccurate in terms of the traits that make X who he is and I don't like that, but I'm otherwise digging the game's non-canon, experimental approach to X. I'm also just happy to see him (and not Zero) in the main roster at all, though I'm sure Zero's on his way to being playable too before long.
There's been a real groundswell around X recently, and this just adds to that, making me hopeful that Capcom finally has something properly exciting in the works for MMX fans... but that's a topic for another thread.
