Hello there,
I don't have an avatar, so I'm making one.
Inspired by this image that coffee posted in some thread here and also every pokemon trainer sprite ever.
I really only have two OCs that I enjoy drawing a lot, and I'll probably do the other after this one.

So I've been staring at this too long of course. I've even exhausted my horizontal flip button.
I can't seem to work that fore-shoe - you'll notice it has a unique blue on it, because I just couldn't find a good shading with the other blues I have. Shame on me, please help!
Then I'm also having issues with the sword, the hair, the face and the hat. By which I mean I am stuck and can't understand what I'm doing wrong and/or how to correct it.
Please also point out anything else I missed/did horribly incorrectly.
Thanks in advance.
EDIT x4 COMBO:

So I just sat down to revisit my palette, which to be fair was in disarray. This allowed me to get that fore-boot closer to where it should be. I also added some extra detail to break up the blankness.
Then I set my sights on the head and just applied stricter rules to define the forms rather than trying to get it to look right through trial and error.
Think I've made some valuable progress here.
Desaturated the blue and green for this version 3. Figured I could always bump all the saturation at a later point, as long as it all goes well together.
More work on the fore-boot and hair/face/hat and simplified the sword majorly.
Version 4 - I messed with the lighting a bit, trying to get it more uniform throughout the piece.
For version 5 I just redid the whole head from scratch and darkened some of the outlines. The redone head was actually inferior, but I learned a lot about the proper lighting for it, so I edited the previous head with what I'd learned and this is what came out.
I really feel like this is pretty close to finished.
Dat hat doe. Fix'd.
Other than that, I just cleaned everything up for version 6.
Calling this done.
