Here is a bit of advice on newgrounds.
Test animations and why you shouldn't upload them
Test animations are short animations including an animated character (mostly madness combat) just doing a form of action, walking, fighting, speaking, etc. most test animations are blammed (when somebody rates low on an Under Judgement, causing it to get deleted) because of their short time and their lack of doing anything, and, since it's a test, it may be animated poorly, but, if it's good, it still gets deleted because of the short time and the lack of doing things. In conclusion, it's best not to upload test animations, if you can, please try to upload test animations elsewhere.
Thank you for reading, and have a nice day.
