He didn't say anything about it. In fact, I didn't even realize he had sent it to me for a good while.
A friend sent me some of these via e-mail. Some of them you've already seen, but seem to be in better quality. The one of Eggman taking some SatAM influence is interesting.
Looks like Jet had more wing-like hands and talon feet. Amusing that Blaze's feet in the middle image look like Big's.
Those Sonic and Tails renders look... different (Not the models just the positioning of them). Sonic 4 promo art to be?
And he actually looks a lot better that way. Less "Original-the-character-esque". That outfit on Blaze is cool, was that ever used or is it concept art?
Trippy of Nightsintodreams.com seems to have a higher res version http://www.nightsintodreams.com/NiD/conceptart/Nights034.JPG
I've never seen that Knuckles render in the back: http://orangeunicorn1984.deviantart.com/art/Knuckles-48-Bop-Bag-Box-216416660
I like that Blaze with the alternate outfit. They totally should have used that somewhere! I've seen that Riders concept art before (in this topic, I think) and I gotta say, Tails with orange hands just looks weird, even if that is his natural hand colour. They look like they should be white, even without gloves... Of course it might just be the bigger-than-torso-style Riders hands that bug me, 'cause gloveless Tails doesn't really look that strange in Sonic X...
Actually, Sonic with blue arms is what looks weird to me. I know it's supposed to be a jacket/jumpsuit, but it looks awkward.
I wish they'd kept that design, it's a lot more consistent with the enemy designs in Tails Adventures. You'd think that they'd realise wings are the biggest defining feature of birds.
