Well...if you look at your battler here you will notice that the main emphasis is placed on his hair and his feather. Or at least it is in my eyes. That is what catches my attention. The wealth of curl in his hair and the large nature of the feather and the fact that it's appears as though there are actually two feathers, not one, stands out to me. That said...if I were creating this charaset that too is where I would place my emphasis.
Now I'll try to help where I can...
Head
Enlarge and double up the feather. Add a yellow tint to the feather.
Remaster the hair. Drop it to his butt and add some curls. Go into depth with the shading. At least five shades. One base color. One lighter than base, and three darker than base colors works well in monotone shading.
Body
Give him those wicked shoulder pads. Remove the white padding between his legs. In the battler his shirt goes beneath the belt line.
That's about all I have right now for you.
All in all I think you did a fantastic job for a beginner.
