[WIP] Head Sprite

[Korvo]

This is a sprite for a game I have been working on, I'm rather new to pixel art and would much appreciate C+C, thank you.

Hair doesn't shade like simple solid objects. Diffuse shading tends to be less significant and highlights tend to be more significant and follow strand direction.
Big hair and ears floating on the hairs surface make the head appear very wide despite the relatively narrow face.
Skin colours are all of pretty much a fixed hue and have little contrast in the midrange.

Wow that looks awesome, thanks for the tips I have always had problems with hair.

Ok, so I have been working with these shading styles you used and I was able to do the back but I am having trouble applying the thin aspect to the side view it keeps coming out looking too big. I also replicated the front view maintaining the jaw structure. I appreciate the help

Here is a door I made a while back and I would like to improve it, critique please.

The door really looks like it was color reduced O_o..

I suggest you dont use black lines.. and shade it acording to a light source. Your shading is very random and the light comes from multiply directions. And it doesnt really have any depth.

[Korvo]

Hmm thank you I made this a while back and I like to think I improved on some of these things but in truth im not sure I could do it much better xD

Thanks for the comments I will try to improve on these things a bit more

UPDATE:
 

Is that right? C+C please.

[Ar]

Not bad but not so good. You used too many colors on hairs, especially on side view. His lips looks like rabbit, its 'cleft lip' (look on edit animation).
Edit for ya:

[Korvo]

Ok, I will try to come up on with an edit.
