Would like some advice

[EpicJ]

I literally just joined, and i'm assuming a lot of you are professional pixel artists, or at least know what you're doing.
So i would like some advice on how to improve and such.
I do small simple pixel art as a sort of hobby, but i wanna get better at it.
So, this is what i consider my 'best'.


Is it good?
What do i need to work on?
Any criticism at all would be great.

Also i don't get this interface or what half the buttons do what is all this i'm so confused.
Also i didn't read the rules beforehand like an idiot so sorry if this violates any of them i'll fix it shortly

Disclaimer: Well I'm not a professional pixel artist nor am I sure of what I'm doing.

Well I think it looks nice but I'm not sure what I'm looking at nor the perspective it wants to show.
The shading is a bit confusing as I can't see what these shades pieces are.
Also the eye looks like it has lots of noise and has an unnecessary amount of colors (one of the colors just gets used in 1 pixel, also the eye has more colors then the rest of the image)
Also the light shading and parts of the eye looks like banding to me (if you don't know what it is just google it )
