A very nice looking background from Parodius Da!, for the Super Famicom. It's a stage filled with bubbles, bunny enemies, bunny girls in bubbles and it's some kinda of heaven where everything is trying to kill you, like every other stage of Parodius. This stage is infamous for having a giant covered naked woman as a boss. She shoots enemies to deal with the player. The original stage uses parallaxing, so I recommend putting it in the background for a very nice effect.
This one could look really smooth as a bonus background if you replaced the stars with some powerup constellations or something. Could also be cool with a bit of work to set up some parallax too. Good work.
I'm a bit surprised it eats up so much palette space lol, but them's shmups.
