it seems to me that you're used to draw the boundaries and then fill in with colors.
instead I think you can gain a lot more if you try to use colors as overlapping layers: do not try to see "single feathers" but instead "spots of colors of same intensity". Did I explain it correctly? this will aid you in a better shaping of the object as well as detailing a lot more than you're using right now.
if you didn't understand I'll try to show you something this evening when I'm not at work

ah thanks man, i've been trying for those two days .. and it didn't work ..
can you show me the something ?

It looks okay so far, but I definitely recommend using some references.







and the like.

Right now, the proportions seem off, the beak isn't hooked enough, the feet seem a bit small, and the colors are a bit off.

However, the technique being used on the head so far is pretty decent,  so it seems to me a few references will help this piece take off.

thanks so much for helping ..

here is a new shading i've made so far

guys ? 

well done, keep going

Is it good or bad? Please C+C him I want to make it awesome for my friend. Be as hard as you can so I can learn more about spriting and other. Thanks in advance.

edit his legs, feet.
both-sides' parts cannot be in the same level of volume, outline the helmet -dark colors-.
each arm needs to be in a different position, also his stomach makes him fat,you need to reshade it after smoothing the outlines.

anyway,it's a simple-beautiful thing to be gifted to your friend ^__^
