>>2259386Not trying to antagonize you for not being 'the best'. There are just a some things that prevent it from being pixel art. Like all art, It can be remedied with study and practice.
Focusing on building palettes and keeping your colors focused can improve your pixel art. Learning color theory can help you build minimal colors and palettes instead of using the blur/brush tool, or just choosing too many colors.
Paying attention to values and leaning to minimally represent plane changes can also help you. You can practice this by studying plane based references and sticking to only colors 3-6 colors without relying on blending.
Study other people's work. Large scale or small scale, the they all use the same fundamentals/rules. With large scale pixel art, your ability to draw/paint, or lack therof, becomes more apparent. So practice drawing and/or painting on the side if you wish to improve.
Here's a low tier edit. I kept the colors the same to show how the palette could be shrunk.
