^ your images are screwed up... and no, it's a PS, it was posted just earlier... =__=
The weapons bays seem to take an age to open. Fair enough that this is the prototype, but I would expect them to be a hell of a lot more snappy on the production model.
The main weapons bay doors also don't seem to fold like the F22's. While this would cut down on complexity and save on weight, it would also increase drag. Hopefully this would also be modified from the production version.
