Thanks for the kind words lief.  I'm kinda new(?) to pixelling (started around mid february), and this is my best work yet. *too ashamed to post others*. 

nose looks slightly flat maybe?

Yea, i see what you mean, ill give it a go later on

i'm thinking seeing you're going low color, why not really low?  you can cut at least 4 shades out of that, maybe more (helm?).

I wasn't really aiiming for low colour, i just chose colours that suited ...BTW whats helm?

hair is very detailed all the way through it.  better effect might be achieved by highlighting areas of the hair with the amount of detail you have applied, and cutting back slightly for the rest.  This would also actually create the illusion of greater detail.

Yea this was the first time for me to create anything semi-detailed, and the hair really had me stumped for a fair while.  Although i think it looks reasonable, I would really appreciate any more tips and pointers to make it look better

EDIT: I just noticed helm is another member here....is that who you were referring to?
