I'm currently trying to make a basic grassland level, but even if I seached and looked through the results I couldn't really find anything. Even mechdragon says he has trouble with this kinda thing. Does anybody know of anywhere I can get a good background for my level?
You really need to be more specific as per the rules. What style and since there's so many grassland backgrounds and other backgrounds that fit with grasslands, can you provide a reference image for what you're looking for?
I’ve found nice backgrounds in Squishy Rex’s GFX Pack. You can see my favorite grassland background in use if you play the first level of the demo of my new game, SMBX64 - The Abduction (link in my signature below)!
