Recently, I ripped the Survival Mode stage backgrounds.
I've tossed them on a new page of my Judgment fansite, which can be found here.
The one above (The boss stage) is my favourite, but I recommend taking a look at all of them.
Something interesting I've noticed is that some of the stages for Isuka's side-scroller mode (GG Boost Mode) remind me of the art style used for Judgment's side-scrolling Story Mode stages. Namely, Fossil Hamlet and Castle Ruins. I find that neat.
I have begun work on rebuilding the Story Mode stages from sprite ripping, but it is far more difficult and time-consuming due to both their size and the scrolling parallax effects. I have to take some artistic liberties, so they will be more a representative example of all of the visuals on the stage as opposed to a 1:1 rip which would be impossible.
Here is what I've gotten so far, which is only a tiny fraction of the first stage. This will be a very long term project.
