My first large pixel that I was proud of. I'm going with a different style these days but who knows, that might change.

Oh wow, thank you very much for that! Yeah you're totally right and I'm still working on learning color and composition. But its nice to get some feedback = )
It's better than your previous work, but your main issue is still flat and washed out colours, a lack of contrast, and the fact that your colours don't convey the shapes you want them to. You also have a lot of extra colours, which makes it harder for you to rapidly adjust the colours, because doing so brings out a lot of isolated pixels (noise) which you need to adjust manually.
Be diligent in using as few colours as possible. It's not a limitation, it's a tool that makes it easier for you to make adjustments.
Here's a very quick edit.
