Hello I did this a few weeks ago and I think it looks nice. Can I have any reviews or ideas to improve?

Also, I posted an animation here yesterday but it got deleted because of bad reviews. But the only review it got was a 4 star rating so I don't really understand. Honestly it's not that bad since it looks like a 5 years old made it, but I'm scared that every thing I make will get deleted. Honestly if this gets deleted too I'm not gonna stay on new grounds except for getting music for gd.
