How can I make pixel art look great ?

Hello,
I recently tried to make a pixel art game but it seems it deson’t work, in fact, I just tried to use one of my pixel art creation in Unity but it looks awful even with a pixel perfect camera

I tried all of the settings available of the pixel perfect camera but it keeps saying that I am using an odd-numbered resolution.
If someone can tell me how to change this resolution or any issue to make my small dinosaur look great, I would appreciate it.

Unity recently did a blog post about this. Maybe it’ll help: How to setup your 2D project for retro 16-bit games | Unity Blog | Unity Blog
