oh great you didnt recolored the armor, nice iniative
ugh, remove the blood under his eyes. if you look at the orc on the art box where war3 got shipped in, or the initialization screen with the bad-mouth orc he have brown, green, yellow, and a mix of yellow-green as colors. when i did my orc spearthrower, he was completly green, but something was missing. the human face isnt tan, but its the global color, we have shades of blue, red green, brown. same thing for the orcs, their general color is green but they have the shades i mentionned. you might want to do a bigger nose, and show the inside of the nostrils
now i recommend taking in reference this wallpaper;

for adding the shades of yellow and all of these colors i simply pen'ed them and then used smuge it gave this;
instead of this
