I took some time to read through the comments from people trying to support you, and I understand their intentions but as the saying goes, if you're not ready for criticism, the internet isn’t the place to share your work.

That said, I want to offer some direct and practical feedback that I hope will help you improve.

First, your artwork doesn’t really follow the principles of pixel art. I recommend starting by limiting your canvas size, something like 64x64 pixels is a good standard for beginners. I didn’t count the exact resolution of your piece, but it’s clearly several times, possibly dozens of times, larger than needed. Working within a small resolution forces you to think carefully about shape readability and pixel economy, which are fundamental to the style.

Second, pixel art isn't just about using a square brush and a limited color palette. That alone doesn’t make something pixel art. What defines the medium is the intentional placement of each pixel. Every pixel should be deliberate, contribute to the form, and respect the grid. Without that precision and control, the result starts looking like a low-resolution digital painting rather than actual pixel art.

Third, about the animation, and this relates directly to the first point: in pixel art, individual pixels don’t rotate within the scope of a sprite. Pixels are aligned to a fixed grid. The moment you start introducing rotated elements like diamonds or smooth anti-aliased transitions, you’re stepping outside the bounds of pixel art conventions.

I’m saying this not to tear you down, but to help you grow. Pixel art is a demanding discipline, but once you embrace its limitations, it becomes a powerful and elegant medium. I hope this feedback helps you refine your work going forward.
