While we're nitpicking designs, I'm not a fan of Rogue's "anime eye which is drawn through the hair lock" thing. Is her hair loose-leaf? I hate that design choice in some anime and it is a little annoying they decided to go the Joe Mad route and ape it here.
Magneto's high heels are also a little silly. Only pirates can get away with that, and he's no pirate. Going with Kubert's Toad design for Ultimate X-Men is cool, though.
Wolverine looks fine, which he should. It's HIS show after all.
Least we'll finally get to see characters like Dust and Domino make major contributions, for those who actually like them (I don't). I'm still preturbed by the lack of Colossus in a lot of stuff, but I'm getting used to the idea. It isn't the first or last time he's shafted in an X-Men cartoon. Hopefully when they truck him out 1-2 times a season for token guest shots, he at least gets more of a moment than throwing Wolverine.
(For those who claim, "Colossus is in promotional material", I need only state that AVENGERS: UNITED THEY STAND promoted Captain America and Iron Man heavily in promotional material and in the intro animation, and they each guest starred in only 1 episode. Promotion has nothing to do with appearance, sometimes.)
Juggernaut looks a little top-heavy, but fine. I'm looking forward to the Hulk fight here more than in the DTV. This show will at least have more context, and thus the fight will have more meaning than a simple smack-down. It represents a shift to X-Men cartoons; usually they don't allow non-X or mutant superhumans in, because some could say it complicates things. Many people don't understand why the world hates mutants but usually embraces non-mutant superhumans, who often are more powerful than many mutants. There's good reasons for this but most cartoons haven't wanted to complicate things.
I must say I'm not looking forward to time travel or aliens again. Those are annoying distractions to the themes of the X-Men, that get rehashed endlessly. Mojo's a crap villain. When I tune in to watch mutant heroes fight for a world that hates and fears them, interdimensional TV warriors is glaringly distracting. I liked how EVOLUTION kept things grounded more. No aliens. Alternate dimensions or time travel were used very, very sparingly. The 90's show set the standard, but often got carried away with aliens and time travel where the themes of the X-Men were sometimes lost in the cosmic mire.
I get that aliens, time travel, and alternate dimensions are all part of the X-Men mythos. I simply see those parts as an annoying tumor that often are used as excuses to negate any character or franchise growth, and removing them truly shows what a writer is made of. Not just anyone can write the X-Men.
