First Spriting Attempt!!

Look what I made! I have always wanted to do some sprite attempts but for one reason or another never bothered doing so, the closest I've ever got was when I recolored some Pokemon Yellow Version sprites back in, sheesh middle school!
This is Molly, one of the characters from my comic Astronautical. I initially wanted to make this like an idle animation where she'd move her antennae and flutter her wings and twitch her forearms but decided not to.
I like how it turned out, but I'm not sure what I need to work on for my next sprite, I do want to attempt another style of shading for the next one though, specifically dithering.
If there's any fellow pixel artists out there please give me some feedback! And perhaps even some tips for future sprites? I'd really appreciate it. <3
