Wow, the suits look even better in this new pic.
regarding the "stocking" design on the female rangers, it looks GREAT on white, not so much on pink, as it doesn't match any of the rest, or indeed any of the male rangers. White's helmet also looks a lot better from this angle. It may well turn out to be my favourite female sentai suit. Blue also looks even more badass from the side.
Can't really comment on the mecha yet, but I'm not all that enthused so far. Then again, the last time I liked the primary mecha was gobuster, so...
