Welcome Ventricle :-)
Its a nice piece, obviously you already know how to draw and maybe paint.
Some feedback for you in terms of pixel art technique:
1. Dither is not contributing here, its obsucring details and making tetures look too rough.
Dithering is not a requirement for pixel art so maybe practice working without it, then work it back into your art once you learn how its useful.
2. Here's a few colour configurations that push out saturation and stuff while still working together. Pretty random stuff in terms of mood but yeah.

Hope it helps!
See my profile if you wanna contact me coz I don't keep up with messages on here ::-)
I rarely soon so beautifully used dithering, I like it a lot !
