Vector art thumbnail blurry, not blurry in sprite drawer, anyone care to help?

The art might be of enormous size, so Scratch compresses it, resulting it in blurriness.

do you know of any way to fix it?
sorry late reply, think i am in a different time zone

oh nevermind i just had to delete some invisible boxes i used for Fisheye squash effect for the sprites i copypasted into the thumbnail. Thanks so much for helping me find the issue
